Bug#414403: xserver-xorg-video-mga: Error detecting memory on g200e

2007-03-29 Thread Stefanos Papanicolopulos

Could you try increasing the memory to 4, 8 or 16MB in xorg.conf by
adding a VideoRam option in the Device section?


Ram sizes 2048, 4096 result in corrupted display, larger ones result in 
sigint 11 crashes of the server.


I just noted that the last commit of the xf86-video-mga driver at
http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-mga.git says:

  Default mode on G200SE of 1024x768 @ 16bpp.
  The poor thing has so little VRAM that you can't do any bigger than 
640x480

  at 32bpp, so in the interest of having a reasonable screen size...

which implies that there is no error in the ram detection, but it is 
indeed so low.

I'm facing the same problem [in Ubuntu, actually]. I guess it is related 
to bad detection of Video RAM size:


  (--) MGA(0): VideoRAM: 1696 kByte
  ...
  (II) MGA(0): VESA VBE Total Mem: 1664 kB

You'll notice that 1024x768x16bpp = 1536kByte, which fits in the 
detected RAM, while 1024x768x24bpp = 2304 kByte, which doesn't fit.


Actually, I don't know the real amount of video memory, but I would be 
very surprised if it were so little.
