** Description changed:
Binary package hint: xserver-xorg
- Both 7.10 and 8.04 Alpha 6 fail to detect LCD panel on Asus F5N laptop. The
result is incorrect resolution and blurred fonts.
+ Ubuntu 7.10, 8.04 and now Intrepid Aplpha5 fail to detect LCD panel on Asus
F5N laptop. The result is incorrect resolution and blurred fonts.
In detail. Xorg detects LCD panel as "Generic PnP Monitor" with 800x600
resolution whereas in fact it is 1280x800 WXGA 98x98 DPI LCD panel. As a
result, the maximum allowed resolution is 800x600 with vesa driver and subpixel
dithering turned off by default.
One has to manually configure screen in System->Administration->Screens
and Graphics to change display to Generic LCD panel, either 1024x768 or
1280x800. In either case the maximum resolution you are allowed to
choose is 1024x768. If you check "Widescreen Monitor" option and then
select 1280x800, it will fail the test and you are back to 1024x768
mode.
Furthermore, this 15.4" WXGA panel is very sensitive to correct DPI
settings in order to produce clear fonts. One has to make sure there is
a line "DisplaySize 331 208" in xorg.conf Monitor section.
Then after installing the proper nvidia-glx-new driver (which should be
installed by default really, as nv cannot handle GeForce 7000M card yet)
I have to comment that line out and replace it with
Option "UseEdidDpi" "FALSE"
Option "DPI" "98 x 98"
in xorg.conf Device section.
This is not very convenient really, and is hard to figure out to
unexperienced user. What the user sees is that:
- 1. Ubuntu splash at 640x480
+ 1. Ubuntu splash at 800x600
2. Initial 800x600 login script and desktop
3. Resolution is only configurable to 1024x768 max
- 4. Wide screen option produces complete mess
- 5. User gets stuck with 1024x768 stretched out image and blurred screen at
best and 800x600 if they are not so lucky
Attached is the output of dmidecode command, and if there is anything
else I can help you with, please let me know.
