    Hello everyone,

    I have an old laptop with the hate-it-or-hate-it SiS671/771 chip, which is well known to work with almost none of the mainstream distributions out there. Unless you try hard.
    To my surprise antiX came to my attention and, along with PCLinuxOS, is probably one of the few that work out-of-the-box with my graphics chipset! However I still have a small issue and would like to short it out: I want to use an external monitor through VGA port but it seems that after the driver is loaded, I get no VGA output:

    demo@antix1:~
    $ xrandr -q
    xrandr: Failed to get size of gamma for output default
    Screen 0: minimum 640 x 480, current 1280 x 800, maximum 1280 x 800
    default connected 1280x800+0+0 0mm x 0mm
       1280x800      60.00* 
       1024x768      60.00  
       800x600       60.00  
       640x480       60.00  

    The monitor seems to work at a low resolution while on live-USB start screen and while booting.

    Thanks in advance.

    You sure already tried
    xrandr --auto
    or maybe
    xrandr --output VGA-0 --auto

    Also some laptops have a FN F8 or something key to activate the external ouput
    or the output can be dis/enabled in the bios.
    Anyway, its probably not a good sign that xrandr only shows “default” instead of LVDS.

    Might help or not. I gave up on obsolete proprietary drivers with obsolete hardware and newer xorg playing nice together. I just roll with vesa and call it a day.

    But to each their own.

    I’ll post a example of one my unsupported graphics chips and how vesa looks on my old laptop.

    AntiX 17 Full install on IBM T23

    Edit:

    Might help or not.

    After reading the thread myself. I feel I should not have posted it < the link > . I have never seen such a fubar thread on graphics in a long time.
