            Bug ID: 57772
          Assignee: openchrome-devel at lists.freedesktop.org
           Summary: Openchrome detects wrong amount of video memory on
                    KM400/KN400
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: Mr.Madguy at Mail.ru
          Hardware: x86 (IA32)
            Status: NEW
           Version: unspecified
         Component: Driver/openchrome
           Product: xorg

I have a problem with your drivers while using ALTLinux 5.0/6.0 on computer
with EliteGroup P4M800-M motherboard(even with latest BIOS 1.0e) with
integrated video card VIA/S3G Unichrome(32Mb reserved in system memory). It
just hung on blank screen while installing or shows incorrect picture(narrow
stripe with "big" distorted cursor). But WinXP works on this computer fine even
with default drivers. One man on ALTLinux support forum told me, that this
problem is caused by incorrect video memory detection. He suggested to use
xdriver=vesa while installing and add OPTION "VideoRAM" "32768" to xorg.com
after it and it helped. I've tried to change chipset in xorg.com to some other
- it didn't helped. Video memory was detected correctly, but screen stayed
blank. So here is some parts of my xorg.log file that will explain you a
problem. May be you can do something with it.
