Description Vince Negri 2005-09-05 09:04:45 UTC

Ran beta 4 installation on Siemens P2020 lifebook, which has an unusual 1280x600
resolution screen driven from a Radeon chipset.

At hardware detection stage, radeon chipset correctly detected, but screen
resolution not detected (so installation uses failsafe of VGA resolution, I was
glad to see :)

[Aside - the screen resolution was detected correctly on this laptop by SuSE
8.2, but not in later versions...?]

Upon finishing the installation and logging in, pop-up informs me that the
monitor could not be detected automatically and would I like to set it up now. I
click Yes and a Sax2 submodule starts.

There are three tabs - the one initially presented has a list of manufacturers
on the left and resolutions on the right. However, 1280x600@60Hz is not
available as a monitor resolution, even in the generic "LCD" section. The
monitor dimensions/dpi can be set manually in the submodule, but not the resolution!

In the end I cancelled Sax2 and manually edited xorg.conf, copying across the
known working modeline from an older installation.


Simply put, it would be very useful during the installation to be able to
manually specify the monitor X&Y pixel resolution. Alternatively, a few more
options could be put in the generic "LCD" list?

very good report. 
 
I added a 1280x600 selection into the LCD section 
 
  
+#============================================== 
+# 1280x600@60Hz 
+#---------------------------------------------- 
+--> LCD:1280X600@60HZ  { 
+ Option=DPMS 
+ Hsync=31-39 
+ Modeline="1280x600" 61.50 1280 1336 1464 1648 600 601 604 622 
+ Vsync=50-65 
+}

Retested with 10.0 GM -  
 
Initial configuration (offered by Yast during install) was 640x480, but I was 
expecting that as the LCD didn't report it's resolution. 
 
Opted to change monitor resolution, 1280x600@60Hz was offered as noted above. 
However, desktop resolution offered was still 640x480. 
 
On opting to change the desktop resolution, 1280x600 was not offered. I had to 
select 800x600. Seems that the 1280x600 option has to be added in another 
place? 
 
 
Completed the install. Booted to runlevel 3 and ran sax2. Config offered was 
640x480. Asked to change configuration, then selected the option to configure 
monitor resolution. Selected 1280x600 and clicked OK. sax2 bombed out to 
command line - no error message on console or in log file....

yes you are right 1280x600 is not VESA specified therefore I forgot 
to add that resolution to be selectable. I'm sorry 
 
fixed for next version
