View Full Version : [ubuntu] Problems with screen resolution!
March 6th, 2011, 04:54 AM
Hi! I want some advice on my problem, I recently installed Ubuntu 10.04 in my computer, I ran update manager and installed all the actualizations but and I can not set the screen resolution higher than 800x600; I have windos XP installed in another partition and the screen resolution can get to 1028x1024 at 85 hz
I have a Pentium 4, 2.20 ghz, 1gb ram, and the video card is a SiS (Silicone Integrated Systems) 300/305/630/540/730 32 Mb... I don't know what can be the problem :(

I found the solution!!
First I tried adding a new resolution with a mode line and xrandr but it did not work, I got the following message:
"The selected configuration for diplay could not be applied
could not set the configuration for CRTC 135"
So I tried editing the xorg.config file and reboot the machine and voila!! I can change the resolution to 800x600, 1024x768, and 1240x1028...
the settings I used are this:
Identifier "Configured Video Device"
Identifier "Configured Monitor"
HorizSync 31.5 - 70.0
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
Modes "1280x1024" "1024x768"
Lucky for me another person had the same problem with the same video card! so I just copy the settings... you should find a solution for your video card!!
Now it seems that the problem is that my video card is not working properly, since everytime I play a video on Youtube, the computer crashes!!... don't know what to do... I also installed crhomium in order to see if the problem had to see with firefox or the machine, but when playinhg online videos on Youtube the computer crashes... T_T any advice here??

Confirmed, playing youtube videos completely crashes my computer... even if I'm using chromium... installed bleachbit and cleaned the firefox install but just solved the problem temporarily... =(
