Since I updated to 2.6.37, vesafb refuses to work. Booting gives me a blank screen until x starts. 2.6.36 worked just fine. I checked that cat /proc/config.gz | gzip -d | grep FB are identical for 2.6.36 and 2.6.37 to rule out kernel config problems One notable difference is that hwinfo --framebuffer reports different stuff on 2.6.37 than on 2.6.36. On 2.6.37, I get: metis ~ # hwinfo --framebuffer 02: None 00.0: 11001 VESA Framebuffer [Created at bios.459] Unique ID: rdCR.hURrHbQ7JGC Hardware Class: framebuffer Model: "NVIDIA BIOS-P/N@N4739:0" Vendor: "NVIDIA Corporation" Device: "BIOS-P/N@N4739:0" SubVendor: "NVIDIA" SubDevice: Revision: "GW-CLKq" Memory Size: 14 MB Memory Range: 0xf7000000-0xf7dfffff (rw) Mode 0x0300: 640x400 (+640), 8 bits Mode 0x0301: 640x480 (+640), 8 bits Mode 0x0303: 800x600 (+800), 8 bits Mode 0x030e: 320x200 (+640), 16 bits Mode 0x030f: 320x200 (+1280), 24 bits Mode 0x0311: 640x480 (+1280), 16 bits Mode 0x0312: 640x480 (+2560), 24 bits Mode 0x0314: 800x600 (+1600), 16 bits Mode 0x0315: 800x600 (+3200), 24 bits Mode 0x0330: 320x200 (+320), 8 bits Mode 0x0331: 320x400 (+320), 8 bits Mode 0x0332: 320x400 (+640), 16 bits Mode 0x0333: 320x400 (+1280), 24 bits Mode 0x0334: 320x240 (+320), 8 bits Mode 0x0335: 320x240 (+640), 16 bits Mode 0x0336: 320x240 (+1280), 24 bits Mode 0x033d: 640x400 (+1280), 16 bits Mode 0x033e: 640x400 (+2560), 24 bits Mode 0x0362: 768x480 (+768), 8 bits Config Status: cfg=new, avail=yes, need=no, active=unknown On 2.6.36, I get this: 02: None 00.0: 11001 VESA Framebuffer [Created at bios.459] Unique ID: rdCR.hURrHbQ7JGC Hardware Class: framebuffer Model: "NVIDIA BIOS-P/N@N4739:0" Vendor: "NVIDIA Corporation" Device: "BIOS-P/N@N4739:0" SubVendor: "NVIDIA" SubDevice: Revision: "GW-CLKq" Memory Size: 14 MB Memory Range: 0xf7000000-0xf7dfffff (rw) Mode 0x0300: 640x400 (+640), 8 bits Mode 0x0301: 640x480 (+640), 8 bits Mode 0x0303: 800x600 (+800), 8 bits Mode 0x0305: 1024x768 (+1024), 8 bits Mode 0x0307: 1280x1024 (+1280), 8 bits Mode 0x030e: 320x200 (+640), 16 bits Mode 0x030f: 320x200 (+1280), 24 bits Mode 0x0311: 640x480 (+1280), 16 bits Mode 0x0312: 640x480 (+2560), 24 bits Mode 0x0314: 800x600 (+1600), 16 bits Mode 0x0315: 800x600 (+3200), 24 bits Mode 0x0317: 1024x768 (+2048), 16 bits Mode 0x0318: 1024x768 (+4096), 24 bits Mode 0x031a: 1280x1024 (+2560), 16 bits Mode 0x031b: 1280x1024 (+5120), 24 bits Mode 0x0330: 320x200 (+320), 8 bits Mode 0x0331: 320x400 (+320), 8 bits Mode 0x0332: 320x400 (+640), 16 bits Mode 0x0333: 320x400 (+1280), 24 bits Mode 0x0334: 320x240 (+320), 8 bits Mode 0x0335: 320x240 (+640), 16 bits Mode 0x0336: 320x240 (+1280), 24 bits Mode 0x033d: 640x400 (+1280), 16 bits Mode 0x033e: 640x400 (+2560), 24 bits Mode 0x0345: 1600x1200 (+1600), 8 bits Mode 0x0346: 1600x1200 (+3200), 16 bits Mode 0x034a: 1600x1200 (+6400), 24 bits Mode 0x0360: 1280x800 (+1280), 8 bits Mode 0x0361: 1280x800 (+5120), 24 bits Mode 0x0362: 768x480 (+768), 8 bits Mode 0x037b: 1280x720 (+5120), 24 bits Mode 0x037c: 1920x1200 (+1920), 8 bits Mode 0x037d: 1920x1200 (+7680), 24 bits Config Status: cfg=new, avail=yes, need=no, active=unknown So obviously, more modes seem availble on 2.6.36 indicating some edid problem may be?
