I can reproduce the same behaviour when I load the vga16fb module manually. I tested at least 2.6.22 and 2.6.25-rc6. It works though when I pass vga=773 to the kernel. When I load the module, I get the following in dmesg and the screen goes blank: vga16fb: initializing vga16fb: mapped to 0xffff8100000a0000 Console: switching to colour frame buffer device 80x30 fb0: VGA16 VGA frame buffer device This notebook uses the following graphics chip: 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) Any idea what to do? lspci -v 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Unknown device 30c9 Flags: fast devsel, IRQ 16 Memory at e0400000 (64-bit, non-prefetchable) [size=1M] Memory at d0000000 (64-bit, prefetchable) [size=256M] I/O ports at 2000 [size=8] Capabilities: [90] Message Signalled Interrupts: Mask- 64bit- Queue=0/0 Enable- Capabilities: [d0] Power Management version 3 -- Martin Michlmayr http://www.cyrius.com/ ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
