Acer Aspire One 150 bb resolution change in OpenSuse 11.1

Initially had a few problem with setting up native resolution in my Suse. When testing a new setting through sax everything was fine, but after restarting X, system was defaulting into 640x480 with only top left part of the screen visible. So my redemption was as follow:
1. running following command:
Quote:
~> gtf 1024 600 60

gives you modeline settings for your screen:
Quote:
# 1024x600 @ 60.00 Hz (GTF) hsync: 37.32 kHz; pclk: 48.96 MHz
Modeline "1024x600_60.00" 48.96 1024 1064 1168 1312 600 601 604 622 -HSync +Vsync

P.S.: I modified the line a little such way:
Modeline "1024x600" 48.96 1024 1064 1168 1312 600 601 604 622 -HSync +Vsync
You can see, I removed frequency 60.00

2. copy above into your xorg.conf, which can be found in /etc/X11/:
Quote:
Section "Modes"
Identifier "Modes[0]"
# 1024x600 @ 60.00 Hz (GTF) hsync: 37.32 kHz; pclk: 48.96 MHz
Modeline "1024x600" 48.96 1024 1064 1168 1312 600 601 604 622 -HSync +Vsync
EndSection

3. Start YaST and navigate to System / "etc/sysconfig editor".
Then Desktop/Display Manager/DISPLAYMANAGER_RANDR_MODE_auto and replace the default settings with:
1024x600_60 48.96 1024 1064 1168 1312 600 601 604 622 -HSync +Vsync
Alternatively you can manually edit it directly in: /etc/sysconfig/displaymanager

4. Restart your X (or reboot)

Enjoy :)
