Package: xserver-xorg-video-mga Severity: important Version: 1.4.4.dfsg.1-1 Using an OpenGL application I noticed a strange behaviour of xorg: The application and probably the whole X server freezes but I can still move the mouse (there is no access to the window manager menus). Logging into the system via ssh works and I noticed that xorg consumes 95-99% of the CPU. I killed it after a few hours with signal 9, the screen gets blanked but I still cannot access a virtual console. Starting X from ssh seems not to work (stops after displaying (==) Using config file: "/etc/X11/xorg.conf"). dmesg reports [drm] Initialized drm 1.0.1 20051102 ACPI: PCI Interrupt 0000:01:00.0[A] -> Link [LNKA] -> GSI 10 (level, low) -> IRQ 10 [drm] Initialized mga 3.2.1 20051102 on minor 0 agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0. agpgart: Putting AGP V2 device at 0000:00:00.0 into 1x mode agpgart: Putting AGP V2 device at 0000:01:00.0 into 1x mode [drm:mga_do_agp_dma_bootstrap] *ERROR* Unable to bind AGP memory: -22 [drm] Initialized card for PCI DMA. The graphic card is a Matrox Millenium G400 AGP: 01:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G400/G450 (rev 04) 01:00.0 0300: 102b:0525 (rev 04) Driver: mga BIOS settings: AGP Aperture Size 4M AGP-4X Mode Disabled AGP Driving Control Auto Increasing 4MB to 128MB help to prevent this problem but Xorg should keep usable even with 4MB. I attached the log which ends with (EE) MGA(0): [dri] Idle timed out, resetting engine... PS: The (default!??) resolution configured for this card (not long time ago) was "1280x920", not "1280x1024".
