[Bug 1970762] [NEW] liblzma failed to decompress a valid lzma file

2022-04-28 Thread Qianqian Fang
Public bug reported:

The lzma file can be accessed here:
https://kwafoo.coe.neu.edu/~fangq/share/temp/mat.lzma

This file was created using the public domain lzma C library written by
Igor Pavlov. It can be decompressed on Ubuntu 20.04 using `lzma -d`,
based on LZMA SDK 9.22, but on either Ubuntu 18.04 and 22.04, where lzma
is built based on liblzma, it gives a "Compressed data is corrupted"
error.


here is the log on Ubuntu 20.04 - where LZMA SDK based lzma works

```
fangq@ubuntu20_04:~$ lzma --version
LZMA command line tool 9.22
LZMA SDK 9.22

fangq@ubuntu20_04:~$ lzma -v -d mat.lzma
mat.lzma:21.83% -- replaced with mat
```

however, on Ubuntu 22.04, lzma -d does not work (same for 18.04)
```
fangq@ubuntu18_04:~$ lzma --version
xz (XZ Utils) 5.2.5
liblzma 5.2.5

fangq@ubuntu22_04$ lzma -v -d mat.lzma
mat.lzma (1/1)
 99.9 %   1,500.9 KiB / 1,920.0 KiB = 0.782
lzma: mat.lzma: Compressed data is corrupt
 99.9 %   1,500.9 KiB / 1,920.0 KiB = 0.782   
```

Because of this, I also noticed that the official lzma module of Python
fails to decompress this file. I want to add that using `lzma` or `lzma-
purejs` npm module, node.js script can correctly decompress this file.

[Bug 1568604] Re: Mouse cursor lost when unlocking with Intel graphics

2021-10-11 Thread Qianqian Fang
Had this issue occasionally last year on Ubuntu 20.04, but now every
single time in the past week after my laptop wakes up from sleep.

Laptop is an Asus TUF F15 gaming laptop, with an NVIDIA 2060 GPU (hybrid
graphics with Radeon Renoir GPU). CPU is an AMD Ryzen 7 4800H. NVIDIA
driver 460.91.03. Ubuntu 20.04.3 LTS with Xfce 4.14.

Kernel version 5.6.14-050614-generic, dual monitors, one connected to
the HDMI port from the USB-C adaptor (DP-0, connected directly to the
NVIDIA GPU), and the other one connected to the HDMI port on the laptop
(HDMI-1-1, graphics "pass-through" AMD Radeon GPU). see
https://forums.developer.nvidia.com/t/ubuntu-19-04-doesnt-detect-my-
hdmi-display/79577/80

When waking up, the DP-0 port (via USB-C, driven by NVIDIA GPU) does not
have this issue, but the HDMI-1-1 port (via AMD GPU pass-through) loses
cursor.

The workaround Ctrl+Alt+F1 followed by Alt+F7, as provided in #1573454
works. Looking for a permanent fix.

[Bug 1875025] Re: Cannot enter password to unlock session

2020-09-16 Thread Qianqian Fang
I recently added two Ubuntu 20.04 servers to my existing Ubuntu machines
in the lab, and started experiencing something similar to this reported
bug.

the problem happens when I remotely connect my new servers using x2go,
and leave the session idle over >5 min. The x2go remote desktop screen
appears to be frozen, no screensaver or password prompt is shown. The
cursor is shown as an I-beam shape. However if I resize the x2go window,
the desktop resizes accordingly. The only way for me to reactivate this
remote window is to ssh to the server and kill the xfce4-screensaver
process "/usr/bin/xfce4-screensaver --no-daemon"

My xfce4 screensaver is set as a blank screen, locking the screen after
5 min idle.

Please let me know if there is a workaround for this. I do not want to
disable screensaver because it also disables this setting on my other
machines because they share the same home dir via nfs.

[Bug 1863157] [NEW] Petition to bring back file name copy/paste functionality in GTK file chooser

2020-02-13 Thread Qianqian Fang
Public bug reported:

For a very long time, I've never/rarely needed to hand-type file
paths/names - it is extremely slow, error-proning and requiring a lot
more work (reading/clicking/moving cursors) to do this simple task.

Instead, I use tabs in a terminal to navigate, pwd to print, and
copy/paste to another file browser or window to use the full path. In
many file browsers (like Thunar), I could also single click on the file,
and directly paste it to the address bar and it directly gives the full
file name.

But this becomes increasingly difficult to do on the GTK file chooser
rolled out sometimes ago. The file chooser window first removed the file
path address bar, but at least there was a button I can click to show it
to copy/paste. Then, even that button disappeared - after many
frustrating hours, the only way to show the address bar is "Ctrl+L",
after reading many similarly frustrated posts

https://www.google.com/search?q=unable+to+type+path+dialog+ubuntu
https://www.google.com/search?q=unable+to+type+path+dialog+site%3Aaskubuntu.com=unable+to+type+path+dialog+site
https://www.google.com/search?q=can+not+type+path+in+file+selector+linux+site:askubuntu.com

>From the long lists of complains that one can find online (I could
easily find more), I think this just prove that removing/hiding the
address bar is very counter intuitive and should be reverted.

I see where this came from - to mimic Mac OS, like most GNOME
style/appearance was trying to achieve, and this setting maybe cleaner
and easier to attract less experienced users, but for people use Linux
for work day-in-and-day-out, this is highly annoying and counter
productive.

Here I would like to petition to revert the change and bring back the
address bar in the file chooser dialog (which is shared among not just
GNOME, but other GTK based desktops, such as xfce), or at least bring
back the button option.

[Bug 1764924] [NEW] Intel HD Graphics 630 can not use three displays but HD 530 can

2018-04-17 Thread Qianqian Fang
Public bug reported:

My Ubuntu (14.04 LTS) desktop used to have an Intel 6700K CPU and I have
been using the built in HD Graphics 530 GPU to drive 3 external displays
- via DP, HDMI and DVI on the motherboard (AsRock Extreme4).

at some point, I upgraded the CPU to an Intel 7700K, and I realized that
the computer can not output to 3 displays anymore.

using xrandr -q, I can only see two connections - HDMI and DP, but the
DVI output is not listed, nor can be activated.

Based on this intel's page, HD630 GPU is supposed to support 3 outputs,

https://www.intel.com/content/www/us/en/support/articles/25672
/graphics-drivers.html

I am wondering if this is a known issue, or if there is a version of the
xorg intel driver that support 3 outputs for HD 630?

my intel driver is provided by xserver-xorg-video-intel-lts-xenial
version 2:2.99.917+git20160325-1ubuntu1~trusty1

thanks, let me know if there is a workaround.

[Bug 1533675] Re: Screen issue with Java applications

2017-06-01 Thread Qianqian Fang
the pixelated/garbled text in Java applications (particularly severe on
remote java applications) appears to be caused by bugs in the xorg intel
driver for the default SNA acceleration method, see

https://www.mathworks.com/matlabcentral/answers/271637-matlab-starts-but-looks-weird-arch-linux
https://wiki.archlinux.org/index.php/intel_graphics#SNA_issues

the workaround is to create a file
/usr/share/X11/xorg.conf.d/20-intel.conf with the content of

Section "Device"
Identifier  "card0"
Driver  "intel"
Option  "AccelMethod"  "uxa"
EndSection


and restart the X window, this will completely solve the pixlated graphics 
issue. 

However, the UXA rendering method is somehow extremely unstable for my
14.04 LTS with the 4.4.0-78 kernel, only in a few minutes after X window
starts, the xorg process starts to use 80-90% of the CPU load, and
window response becomes sluggish, despite similar glxgears FPS readings
compared to SNA. I switched several times back and forth, the
observation is consistent on my computer. I had to revert back to SNA to
use the computer normally. too bad this is not a real fix.

2017-03-23 Thread Qianqian Fang
sorry, I posted the logs twice.

I just want to mention that my above logs were collected when only 2
displays are attached (in which case, the graphics functions ok),
despite that you can see plenty of pipe A FIFO underrun errors.

do you want me to connect the 3rd cable (to the TV) to trigger the
crash, and recollect the logs?

[Bug 1675204] WifiSyslog.txt

2017-03-22 Thread Qianqian Fang
apport information

** Attachment added: "WifiSyslog.txt"
   
https://bugs.launchpad.net/bugs/1675204/+attachment/4842931/+files/WifiSyslog.txt

** Description changed:

  I have a very strange issue related to Intel graphics drivers (i915)
  with 3 connected on-board displays.
  
  I have a Xubuntu (14.04 LTS with HWE on 4.4.0-66 kernel) desktop
  computer running on a i7-6700K processor and on-board graphics (Mobo:
  AsRock z170 extreme4). I connect it to 3 displays - a 3440x1400 LG
  display (via onboard DP port), a 1920x1200 Dell display (via on-board
  HDMI), and a Sony 4k TV (via onboard DVI and a DVI-to-HDMI adapter).
  
  If I just connect my desktop to the first two displays (not the TV),
  everything works fine (except some minor issues). However, if I connect
  the 4k TV, even the TV is not on, my graphics starts to flicker every 5
  min-ish (window theme turns off and then turns quickly back on); after a
  few flickering, the window theme will disappear, and the screen becomes
  weird - my chrome window will not fresh, or show blank boxes etc.
  
  If I disconnect the DVI connector to the TV (just use the LG+Dell dual-
  display), flickering and crash will not appear.
  
  I want to mention that, when I connect the computer to all 3 displays, I
  was actually able to get video output to all displays (I used arandr to
  configure them). I can even get 4k output to the 4k TV at 30Hz.
  
  I can't find a useful log entry when the flicking or graphics crash
  happens. I can only see a "CPU pipe A FIFO underrun" for pipe A/B/F (log
  attached at the end), but I can see many similar errors in my log and
  the appearance is not correlated to the flickering/crash. The "pipe A
  FIFO underrun" issue was previously reported in Bug#1550779.
  
  I also see "intel(0): HDMI max TMDS frequency 30KHz" entry in my
  Xorg.0.log file constantly, I also do not see an consistent mapping
  between the log entry and the flickering.
  
  Can anyone tell me how to properly debug this? what can I do to get a
  log for what was wrong?

** Description changed:

  I have a very strange issue related to Intel graphics drivers (i915)
  with 3 connected on-board displays.
  
  I have a Xubuntu (14.04 LTS with HWE on 4.4.0-66 kernel) desktop
  computer running on a i7-6700K processor and on-board graphics (Mobo:
  AsRock z170 extreme4). I connect it to 3 displays - a 3440x1400 LG
  display (via onboard DP port), a 1920x1200 Dell display (via on-board
  HDMI), and a Sony 4k TV (via onboard DVI and a DVI-to-HDMI adapter).
  
  If I just connect my desktop to the first two displays (not the TV),
  everything works fine (except some minor issues). However, if I connect
  the 4k TV, even the TV is not on, my graphics starts to flicker every 5
  min-ish (window theme turns off and then turns quickly back on); after a
  few flickering, the window theme will disappear, and the screen becomes
  weird - my chrome window will not fresh, or show blank boxes etc.
  
  If I disconnect the DVI connector to the TV (just use the LG+Dell dual-
  display), flickering and crash will not appear.
  
  I want to mention that, when I connect the computer to all 3 displays, I
  was actually able to get video output to all displays (I used arandr to
  configure them). I can even get 4k output to the 4k TV at 30Hz.
  
  I can't find a useful log entry when the flicking or graphics crash
  happens. I can only see a "CPU pipe A FIFO underrun" for pipe A/B/F (log
  attached at the end), but I can see many similar errors in my log and
  the appearance is not correlated to the flickering/crash. The "pipe A
  FIFO underrun" issue was previously reported in Bug#1550779.
  
  I also see "intel(0): HDMI max TMDS frequency 30KHz" entry in my
  Xorg.0.log file constantly, I also do not see an consistent mapping
  between the log entry and the flickering.
  
  Can anyone tell me how to properly debug this? what can I do to get a
  log for what was wrong?

[Bug 1533675] Re: Screen issue with Java applications

2017-03-22 Thread Qianqian Fang
I have similar issues with Xubuntu 14.04 LTS with HWE (kernel 4.4.0-66)
and Intel Graphics (Skylake i7-6700k with HD 530 GPU).

In my below screen capture, I show a matlab window started on a remote
machine via "ssh -Y" (left), and the same matlab started on the local
machine (right).

You can see the left window show blank text in various places. The file
icons for the two files (initval.txt and wazu2...) on the file explorer
panel also show white stripes (I've seen this on various context).

This seems to happen only with Intel graphics, although I am not sure.

[Bug 1469290] [NEW] Open terminal option disappeared in Thunar context menu

2015-06-26 Thread Qianqian Fang
Public bug reported:

I have a couple of Ubuntu boxes running Xubuntu 12.04 LTS. In those
boxes, the Open in terminal (or alike) option is not available in
Thunar (1.2.3).

At home, I have a computer running Xubuntu 14.04 LTS. The context menu
has the terminal options.

If this is a bug that was fixed in 14.04, it would be nice to have it in
12.04. Otherwise, I'd like to know what was wrong with my 12.04 thunar.

thanks

[Bug 984785] Re: .goutputstream files polluting $HOME

2013-09-03 Thread Qianqian Fang
I am not able to log on my computer (12.04), and I noticed that
everytime lightdm failed to log me in, there is a .goutputsteam-
file and a sed file created under my home directory.

my computer runs nis/autofs with a home directory mapped on a file
server.

I believe the bug I've seen is related to Bug #1004515, but not sure how
it is related to this bug. just post here in case someone can make sense
of it.

[Bug 781459] [NEW] audio input source reset to line in after reboot

2011-05-11 Thread Qianqian Fang
Public bug reported:

Binary package hint: padevchooser

This is an annoying problem starting after I upgraded my xubuntu from
10.10 to 11.04.

My rear mic stop working every time I reboot my machine. After checking
on a number of things, I realize that the input source is set to Line
instead of Rear Mic. I noticed this from xfce mixer, but I suspected
this is caused by Pulse Audio Device Chooser.

Please take a look, and let me know if you need any additional tests to
nail down the problem. thanks

2011-05-08 Thread Qianqian Fang
Please reopen this bug. There is a regression in xubuntu 11.04

If any popup menu is shown on the xfce panel, such as Places menu, or
the context menu of the panel of any plugin, pressing PrintScreen or
Alt+PrintScreen won't do anything.

If any application menu item is displayed, pressing PrintScreen or
Alt+PrintSceen will first hide the menu and then make a screenshot of
the application window. There is no way to screen capture the menus with
the shotcuts.

Making language-selector-zh-* Chinese specific will leave 65-nonlatin

Sadly, 65-nonlatin is terribly outdated, and put Japanese fonts in front

[Bug 720181] [NEW] glibc update breaks NIS compat mode on Lucid

2011-02-16 Thread Qianqian Fang
Public bug reported:

I recently experienced a major slowdown (10 sec)  when logging on the
NIS server at my work place. Our admin Paul Raines found that the issue
was caused by a recent glibc update (2.11.1-0ubuntu7.8 posted on Feb 01,
2011), which appeared to break the compat mode for password settings
in /etc/nsswitch.conf

Observations:

With the latest update of libc on Lucid and setting passwd/group/shadow
as compat, any remote authentication process will take over 10 seconds
to respond. This include showing the login window by gdm/xdm, verifying
password, and any gksu/sudo commands. To test the delay, I followed the
comment #3 from Bug #335584 and ran

 sudo strace -vft -o /tmp/trace sudo true

I noticed two 5-seconds time-out from the dumped log.

Work-around:

After changing passwd/group/shadow from compat to files nis in the
/etc/nsswitch.conf file, the above mentioned long-delay went away.

Here I attached the reply from Paul and my original test. We appreciate
if anyone can double check with the mentioned update and see if there is
a solution for this.

From:   Help Desk -- Paul Raines help at nmr
To:   Qianqian Fang fangq at nmr

I changed /etc/nsswitch.conf so that instead of 'compat' for passwd, group
shadow I have 'files nis'.  This seems to have made the long NIS timeouts
go away.  This means that that '+/-' lines in /etc/passwd will not work
though.  I suggest you file a bug with Ubuntu saying 'compat' mode has
broken in the lastest glibc release which appears to have updated Feb 1st.

 although, the computer is still not completely normal.
 When I select user name, type password in the xdm/gdm

 I did some strace following this comment:

 https://bugs.launchpad.net/ubuntu/+source/sudo/+bug/335584/comments/3

 and the output for

  sudo strace -vft -o /tmp/trace sudo true

 is placed at /space/internal/3/users/fangq/Share/trace.sudo

 I can see there are two 5-second time-outs during this
 command: one at line#28556 and one at #29149. In
 either case, kwafoo tried to send some data through a socket to
 132.183.203.49, which I believe is a computer
 named sake, but it failed with time-out.

 I don't know what sake does in the nis configuration,
 but somehow it does not communicate with kwafoo
 properly. Strangely, the earlier communications
 does work. This behavior is reproducible when running
 the above command.

 Can anyone make heads and tails out of this log file?

 thanks

[Bug 720181] Re: glibc update breaks NIS compat mode on Lucid

2011-02-16 Thread Qianqian Fang
** Description changed:

  I recently experienced a major slowdown (10 sec)  when logging on the
  NIS server at my work place. Our admin Paul Raines found that the issue
  was caused by a recent glibc update (2.11.1-0ubuntu7.8 posted on Feb 01,
  2011), which appeared to break the compat mode for password settings
  in /etc/nsswitch.conf
  
  Observations:
  
  With the latest update of libc on Lucid and setting passwd/group/shadow
  as compat, any remote authentication process will take over 10 seconds
  to respond. This include showing the login window by gdm/xdm, verifying
  password, and any gksu/sudo commands. To test the delay, I followed the
  comment #3 from Bug #335584 and ran
  
   sudo strace -vft -o /tmp/trace sudo true
  
  I noticed two 5-seconds time-out from the dumped log.
  
  Work-around:
  
  After changing passwd/group/shadow from compat to files nis in the
  /etc/nsswitch.conf file, the above mentioned long-delay went away.
  
  Here I attached the reply from Paul and my original test. We appreciate
  if anyone can double check with the mentioned update and see if there is
  a solution for this.
+ 
+ My computer is running Lucid 10.04.2 LTS, with a kernel version
+ 2.6.32-27.

  To:   Qianqian Fang fangq at nmr
  
  I changed /etc/nsswitch.conf so that instead of 'compat' for passwd, group
  shadow I have 'files nis'.  This seems to have made the long NIS timeouts
  go away.  This means that that '+/-' lines in /etc/passwd will not work
  though.  I suggest you file a bug with Ubuntu saying 'compat' mode has
  broken in the lastest glibc release which appears to have updated Feb 1st.

   and the output for
  
sudo strace -vft -o /tmp/trace sudo true
  
   is placed at /space/internal/3/users/fangq/Share/trace.sudo
  
   I can see there are two 5-second time-outs during this
   command: one at line#28556 and one at #29149. In
   either case, kwafoo tried to send some data through a socket to
   132.183.203.49, which I believe is a computer
   named sake, but it failed with time-out.
  
   I don't know what sake does in the nis configuration,
   but somehow it does not communicate with kwafoo
   properly. Strangely, the earlier communications
   does work. This behavior is reproducible when running
   the above command.
  
   Can anyone make heads and tails out of this log file?
  
   thanks

Both machines use en_US locale, with Chinese support installed.

On 06/08/2010 10:58 AM, Scott Severance wrote:
 I'd like to second iEGL's suggestion to remove Hangeul from that font.
 After all, Hangeul is pretty much irrelevant to Chinese, which is the
 focus of that font. And there is already adequate Hangeul coverage
 included by default without that font. Let that font do its job of
 handling Chinese, and let Korean fonts handle Korean (by the way, Korean
 rarely uses Hanja; Hangeul is used almost all of the time). Why should a
 Chinese font include Hangeul?


I kindly disagree. First of all, the issue itself is only related
to an anti-aliasing setting in a fontconfig file. It has
nothing to do with the Hangul glyphs themselves
included in these font. The right solution has been
already provided in comment #8.

Secondly, because Korean people rarely use Han characters
does not mean Chinese won't use Hangul. For the same
reason, LGC people almost never use Chinese, that
won't give you a conclusion that all LGC characters
should be removed from Chinese fonts.
(Hangul are found in many Chinese ASCII arts,
and I believe many Korean literature and archives
have Hanja)

Thirdly, removing Hangul from these two fonts
gain little saving in terms of space. All Hangeul glyphs
are composed of references, and removing them
only save a few hundred KB. The price to pay is
that Chinese users have to install Korean fonts to read
Korean. That is almost tons of MB in space. A
single compact Unicode font is very important for
many mini-distributions and i18n support for open-source
games.

Lastly, Hanguls in Korean fonts and Chinese fonts
have different metrics and slightly different styles.
It is always good to have matched metrics when
displaying a text mixed with different languages.

[Bug 472845] Re: wrong metric for Chinese font in OpenJDK applications

2010-05-04 Thread Qianqian Fang
** Description changed:

  OpenJDK does not display Chinese (or CJK) characters correctly. It
  appears that all Han glyphs were displayed using wrong metric, and is
  only half to 1/3 of the actual EM width.
  
  A screenshot is attached to illustrate the problem. To reproduce, select
  OpenJDK Java 6 policy Tool from the setting sub-menu, then select menu
  File\Open and navigate into a folder with Chinese name.
  
  Notice that the Chinese folder name 中文目录 in the top file name box is
  only half-width, but the Chinese subfolder names in the left panel are
  fine.
  
  This was also reported previously in Ubuntu Chinese forum (in Chinese),
  see http://forum.ubuntu.org.cn/viewtopic.php?f=8t=221482
  
  Creating a link in /usr/lib/jvm/java-6-openjdk/jre/lib/fonts/fallback
  folder does not solve the problem. Also, OpenJDK does not follow the
  fontconfig settings.
+ 
+ 
+ Update: as pointed out by Man Yuan in Comment#4, the font paths for 
wqy-zenhei in fontconfig.propertie sneeds to be updated as well. The font file 
suffix has been changed to ttc after the upgrade to 0.8.34 last year.

I am pretty sure this is related, someone had reported a test in Ubuntu Chinese

The broken one at the bottom is WenQuanYi Zen Hei. The one next to it
is WenQuanYi Zen Hei Mono. I suspect that the wrong metrics is related
to the embedded bitmaps.

I agree that this is likely true for Latin fonts, but for

please do not mix two issues together:

the original report seems to be an issue of prioritizing Japanese
fonts above Chinese ones: the text was clearly rendered by
Japanese-styled Han glyphs (likely vlgothic). This should be
fixed by using the language-specific fontconfig files that Arne is
working on, (or the current language-selector/fontconfig-voodoo
approach).

Arne, can you give an update on this?

the second issue is the preference between microhei/zenhei, or
microhei/bitmap song for Han glyphs. Admit it or not, this is
just a matter of personal taste. It is fine to advocate the preference
you like, but please also show your respect to the alternative
opinions too. Using strong words such as ugly can actually
bring negative feelings to your feedback.

Re: [Bug 149944] Re: CJK fonts should not have highest priority

2010-03-17 Thread Qianqian Fang
I agree with depp that it would be more consistent and
visually pleasant if the dedicated Latin serif fonts are placed
above CJK ones.

There are lot of limitations for the Latin glyphs in CJK fonts,
particularly in UMing/UKai: they are mono-spaced, with
neither hinting nor kerning, and have never been optimized
as Dejavu/Droid/Liberation etc. The embedded bitmaps
are quite rough: the baselines are not aligned, the serifs
are not consistent and lots of glyphs fills the whole EM
which glues the adjacent bitmap glyphs together (for example,
zr and 200 as in Arne's screenshots).

Monospaced Latins are primarily good for console or
editors; in other places, they are much inferior to
proportional ones. To put Dejavu serif or Droid
Serif above UMing is highly desired for CJK locales.

[Bug 468898] Re: FreeSerif should not be default Serif font

2010-03-16 Thread Qianqian Fang
For Chinese (or CJK) users, Firefox's choice to use serif as the default
font is also questionable. Not only because it is inconsistent to the
default font style for desktop (i.e. sans-serif), but also the non-
optimal rendering performance of the existing serif CJK fonts (Song/Ming
styles). Most users don't care the font categories when browsing web
pages, but prefer consistency and clarity for on-screen use.

Perhaps someone should file a bug to Firefox upstream directly.

[Bug 467979] Re: Chinese font not render in the same font-family

2010-03-06 Thread Qianqian Fang
This is the typical scenario where Japanese fonts overwrite Chinese
fonts. The default fontconfig settings put Japanese fonts in front of
Chinese fonts. Because Japanese fonts only cover a small fraction of
Kanji, when rendering a block of simplified/traditional Chinese text,
the missing ones will be rendered by Chinese fonts with full-coverage. I
had proposed solutions to this issue, but the fontconfig developers are
slow in responding:

https://bugzilla.redhat.com/show_bug.cgi?id=499902
http://bugs.freedesktop.org/show_bug.cgi?id=20911

if your firefox and other programs handle Chinese properly, then it must
be webkit-based programs ignore some of the additional CJK specific
fontconfig settings.

[Bug 521163] Re: WenQuanYi Zen Hei is prioritised above Japanese fonts for Japanese language text

2010-02-12 Thread Qianqian Fang
have you installed the package named language-selector?
you might need to add CJK specific fontconfig files
by installing this package, and then activate Japanese
settings by

 sudo fontconfig-voodoo -f -s ja_JP

this is a Ubuntu hack for solving the CJK language
conflict. I've proposed a more systematic solution
to fontconfig upstream, but I've got no response yet,
see
