I've been searching and reading message boards and mail lists for days and haven't found anything. It seems that the driver is not setting the proper video timings. I have tried using the vesafb driver and my hardware works fine. If I try to use the intelfb driver my monitor either complains and shuts off or I get text and graphics that is horizontally squiggly (if that makes sense). I tried initializing the driver in several modes with parameters such as: video=3Dintelfb video=3Dintelfb:640x480-16@60 fbset -i reports the following: mode "1024x768-70" # D: 75.002 MHz, H: 56.477 kHz, V: 70.071 Hz geometry 1024 768 1024 768 32 timings 13333 144 24 29 3 136 6 accel true rgba 8/16,8/8,8/0,0/0 endmode Frame buffer device information: Name : Intel(R) 915G Address : 0xd0000000 Size : 8253440 Type : PACKED PIXELS Visual : TRUECOLOR XPanStep : 8 YPanStep : 1 YWrapStep : 0 LineLength : 4096 MMIO Address: 0xcfd80000 MMIO Size : 524288 Accelerator : Unknown (42) I am using kernel 2.6.12. Any help or ideas would be appreciated. Thanks, Dave Kavanagh ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
