graphics memory misallocated on Matrox Millienium II AGP 4M card

[Nick Briggs]

Binary package hint: xserver-xorg-driver-mga

Using Ubuntu 8.10 beta LiveCD, resurrecting a Compaq Deskpro with a Matrox Millenium II AGP graphics card, either the X server, or the mga driver, overestimates how much video memory is present, resulting in aliasing of segments of the screen (move a window in one place, and other parts of the screen change).

Under 8.04.1, it selects a screen resolution of 1280x800x24bpp

Attached initially are the xorg.0.log and lspci -vvnn output from the 8.04 system which works -- I'll try to add the 8.10 output if I can see enough on the screen to do it!

Still a problem in 8.10 release, and adding xorg.conf configuration to tell it 4MB video memory doesn't change anything.

Hi briggs,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the latest development release of Ubuntu? (ISO CD images are available from http://cdimage.ubuntu.com/releases/)

If it remains an issue, could you also attach a new /var/log/Xorg.0.log?
Thanks in advance.

Hi Bryce --

This still remains an issue -- I have booted the system with Ubuntu 9.10, and the new Xorg.0.log is attached.
