start xubuntu in VGA mode

**linopinolino** · July 29th, 2012

Hi Guys
I just installed Xubuntu 12.04 on my new machine a ThinkPad a22p 12 years old (or maybe more) with a 16bits 800x600 screen.
I see the video "duplicated". I managed to solve the problem with the life version running on a CD by using the argument VGA=788, but in the installed version I do not manage to get solved.
This is what I done with no success:
Edit the boot parameters in /etc/default/grub
uncomment GRUB_GFXMODE=800x600
I also added a line VGA=788

I edited the grub command at boot adding vga=788

no results

thanks for help!

did you remember to run update-grub after? otherwise the changes to /etc/default/grub don't actually get written to the grub config

Code:

sudo update-grub

Hi guys, at the end it was pretty easy, I just had to ad a xorg.conf file like this one

Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
SubSection "Display"
Viewport 0 0
Depth 16
Modes "1024x768"
EndSubSection
EndSection

I tried with vesa driver, nobody can suggest me a better driver for a ATI Mobility M3 (16 MB)?

Thanks
