    start xubuntu in VGA mode

    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

    That chip is no longer supported by the proprietary driver, so continue to use the default driver.
