Problem with the screen resolution on 12.04
Refer to choosing correct driver package here: Linux Graphics Drivers from Intel
Possible solution is:
sudo dpkg-reconfigure -phigh xserver-xorg
sudo reboot
Other way:
Step 1. Create mode line by using gtf
Thus if your output have 61.0Hz frequency:
gtf 1280 800 61.0
- this command will calculate your Modeline for 1280x800
Step 2. Create new mode for xrandr
xrandr --newmode <value of your modeline without word "Modeline">
Step 3. Add new mode to output
xrandr --addmode VGA 1280x800_61.00
And if commands above DON'T bring any errors:
Step 4. Choose your new mode
xrandr --output VGA --mode 1280x800_61.00

I just installed Ubuntu on my laptop. The screen resolution is stuck in 1024x768. The screen is made for 1280x800. When I run
xrandr
I get:xrandr: Failed to get size of gamma for output default Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600 61.0
1280x800 isn't offered and I get gamma size error. I was going to look into the
Xorg.conf
file but I couldn't locate it.1280x800 was displayed in Windows 7 and I think it is being displayed in Grub before Ubuntu starts also. Here are some details about my computer:
- CPU: Intel atom D2500 1.86GHz
- Chipset: Intel 945GSE+ICH7M
- LCD: 14" TFT 16:9
- Resolution ratio: 1280*800
- Video Card: Intel integrated GMA950
Does anyone know how to fix this?
