Created attachment 373982 [details] Xorg.log Description of problem: Black screen in X with F12 Environment: Matrox G550 TFT with 1280x1024 resolution at DVI connector How to reproduce: Boot Fedora-12-i686-Live-KDE Display ends up with black screen and parameter out of range info. Switching to text console with ALT-F2 seems to work but new output corrupts the display. Toggling between ALT-F1 and ALT-F2 restores temporary the console display till next output. Observations: The default mode of the matroxfb kernel driver seems to be the culprit. In dmesg is this: matroxfb 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 matroxfb: Matrox G550 detected matroxfb: MTRR's turned on matroxfb: 640x480x8bpp (virtual: 640x26214) matroxfb: framebuffer at 0xFA000000, mapped to 0xf8000000, size 33554432 fbcon: MATROX (fb0) is primary device fb0: MATROX frame buffer device "video=matroxfb:vesa:0x11B" from kernel doc matroxfb.txt on the kernel command line seems to have no effect because matroxfb_base is loaded as a module. But "matroxfb_base.vesa=0x11B" does the trick. In dmesg is this: matroxfb 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 matroxfb: Matrox G550 detected matroxfb: MTRR's turned on matroxfb: 1280x1024x32bpp (virtual: 1280x3276) matroxfb: framebuffer at 0xFA000000, mapped to 0xf8000000, size 33554432 fbcon: MATROX (fb0) is primary device fb0: MATROX frame buffer device The text console and X are now working as expected. Xorg.log is identical with and without "matroxfb_base.vesa=0x11B" "vga=795" on the kernel command line is also working. But this involves kernel vesafb and kernel matroxfb fails to start.
