[Ubuntu-x-swat] [Bug 1821882] Re: Screen is very dark and brightness cannot be adjusted

2019-03-27 Thread Pierre Equoy
I tried the same while blacklisting nouveau driver in grub:

$ cat /proc/cmdline
BOOT_IMAGE=/casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper quiet 
splash modprobe.blacklist=nouveau ---

This time, I have "acpi_video0" in /sys/class/backlight, but the result
is the same. The screen is very dark.

/sys/class/backlight/acpi_video0/brightness is 100 by default. I can
modify this value with

$ sudo su
# echo 60 > /sys/class/backlight/acpi_video0/brightness

and the brightness actually changes to something even darker. If I try
to set it over 100, I get:

write error: Invalid argument

2019-03-27 Thread Derk Willem te Bokkel
stranger and stranger .. if you install kernel 5.0.0-8.9 at the first
boot into any new install partition before changing any thing else .. it
does not fix the issue .. once you return sda1 to being grub master ..
neither sda7 nor sda6 will keep lightdm running ..both briefly flash
lightdm login screen and then blank out screen , briefly showing a
cursor ..  a long hold down of power button does eventually powerdown
machine .. note: can't even get to consoles .. not a nice fail.

note resetting grub back to the "new install version"  works but there
is a stutter in lightdm .. it shows briefly blanks for 2 seconds then
shows again and and you can login..

only other way into partition is through recovery boot option, or via a
chroot.

this is now using xubuntu-am64-desktop.iso -beta version ( two installs
sda6 and sda7 )

I'm beginning to think that using a chroot to reinstall/or update the
kernel might be a "work around only" for the issue .. as a native update
does not work ..

I'm going to test this further .. replace sda6 and sda7 sequentially and
see what happens using chroots for updates   more later .. any ideas
what else to look for or check?

2019-03-27 Thread Derk Willem te Bokkel
okay still bug present in xubuntu-disco-amd64-desktop-beta.. still uses
kernel 5.0.0-7

updating from proposed with  kernel 5.0.0-8.9  it works properly

i.e. any linux os partion can be used to install grub and another partion with 
linux can be 
selected and boot normally 

e.g. beta install is on sda7 another linux os version is on sda1 which is used 
to install grub to /dev/sda  thus sda1 is master/main linix os used .. the beta 
on sda7 will start lightdm but it flickers on and dies when using kernel 
5.0.0-7 
but when using kernel 5.0.0-8.9 it works properly lightdm stays running and 
does  not even flicker...  the only apparent difference is the kernel selected 
..

[Ubuntu-x-swat] [Bug 1821505] Re: [radeon] screen cannot be turned back on after some time of inactivity

2019-03-27 Thread Hark
Here is the workaround for the problem:

The bug is in the package xserver-xorg-video-radeon 7.7.0, it is fixed in the 
later versions.
Until it is fixed in 16.04 LTS, take the package from the newer releases. 

In this example, we'll pull it from 16.10 (Yakkety Yak):
a) add the line at the end of the /etc/apt/sources.list file:
deb http://old-releases.ubuntu.com/ubuntu yakkety main
b) add file "yakkety.pref" to the /etc/apt/preferences.d
c) sudo apt-get update - this will load new repostiory and refresh the 
preferences
d) sudo apt-get upgrade - this will pull xserver-xorg-video-radeon package 
v7.7.1, with fixed bug.
e) log out from X

That's it. After login, wait for the screen blank and wake it with key
press or mouse action.


** Description changed:

  When using my AMD Radeon X1300 card, if the screen turns off due to
  inactivity, it cannot be woken up by moving the mouse or by hitting a
  key.
  
- WORKAROUND: Type in a terminal:
+ If you type in a terminal:
  xset -display :0.0 dpms force off
+ you can wake the screen normally.

addional clarification .. if sda6 (recovery booted or chrooted)
installed grub then sda6 boots with some brief flashing normally. if
sda7 or sda1 (recovery booted or chrooted or a normal boot for sda1)
installed grub then sda6 would boot and lighjtdm would briefly flash
onto screen and the disappear (blank screen) showing just aflashing
underline cursor.

so xorg video drivers appear  NOT to be involved. except maybe as kernel
i915 modules missing I have not checked

*** This bug is a duplicate of bug 1819943 ***
https://bugs.launchpad.net/bugs/1819943

this effected only the more recent installs

you have miss understood the details in the initial report .. the system
would boot normally as long as the grub used (installed) was from the
install partition (sda6 or sda7) .. if another partition was used to
install grub the lightdm would appear briefly and then crash or vanish
to a underline flashing cursor

the video system did work it would flash once on start-up but come back
in about 5 seconds or less is the correct (ie this partition installed
the grub version used)

the main sda1 partition always worked .. only difference was the kernel image 
used .. 
I have not yet checked to see if the sda1 5.0.0.7 image fails currently but it 
worked fine before.

the installation of the newer video drivers did not fix this issue!!! It
remained as long as a 5.0.0.7 kernel was selected to boot sda6 or sda7

sda1 was not effected.

[Ubuntu-x-swat] [Bug 1821882] [NEW] Screen is very dark and brightness cannot be adjusted

2019-03-27 Thread Pierre Equoy
Public bug reported:

Device: Dell Precision 7530
In the BIOS, the Switchable Graphics option is deactived, which means only the 
nVidia GPU is used.

When booting 19.04 beta live USB, the screen becomes very dark and
brightness cannot be adjusted. (The same issue happens with 18.04.2)

There is only a "nv_backlight" in /sys/class/backlight/ (i.e. no
intel_backlight):

$ ll /sys/class/backlight/
