I've been beating my head against this one for a while now, so any ideas will be appreciated!
The CRT output from my thinkpad X40 has slightly wrong resolution, which creates a band of junk at the top and loss of same-size band at bottom. The video controller is Intel Corp. 82852/855GM Integrated Graphics Device.
Comparing my log file with that of another X40 user who apparently does not have this problem, I suspect the problem is related to agpgart and the
available video RAM:
GARTInit: Unable to open /dev/agpgart (No such device)
(WW) I810(0): /dev/agpgart is either not available, or no memory is available for allocation. Using pre-allocated memory only.
The problem is not the lack of /dev/agpgart or kernel support for it--
I have both, and agpgart module is loaded in the kernel. I think the problem is the memory. I have:
I810(0): VideoRAM reduced to 8060 kByte (limited to available sysmem) (--) I810(0): Pre-allocated VideoRAM: 8060 kByte (--) I810(0): VideoRAM: 8060 kByte
whereas the other lucky user has 8192kb:
(II) I810(0): I830CheckAvailableMemory: 954364 kB available
(II) I810(0): Will attempt to tell the BIOS that there is 8128 kB VideoRAM
(II) Loading sub module "int10"
(II) LoadModule: "int10"
(II) Reloading /usr/X11R6/lib/modules/linux/libint10.a
(II) I810(0): initializing int10
(WW) I810(0): Bad V_BIOS checksum
(II) I810(0): Primary V_BIOS segment is: 0xc000
(II) I810(0): VESA BIOS detected
(II) I810(0): VESA VBE Version 3.0
(II) I810(0): VESA VBE Total Mem: 8128 kB
(II) I810(0): VESA VBE OEM: Intel(r)852GM/852GME/855GM/855GME Graphics Chip Accelerated VGA BIOS
(II) I810(0): VESA VBE OEM Software Rev: 1.0
(II) I810(0): VESA VBE OEM Vendor: Intel Corporation
(II) I810(0): VESA VBE OEM Product: Intel(r)852GM/852GME/855GM/855GME Graphics Controller
(II) I810(0): VESA VBE OEM Product Rev: Hardware Version 0.0
(II) I810(0): BIOS now sees 8128 kB VideoRAM
(--) I810(0): Pre-allocated VideoRAM: 8060 kByte
(==) I810(0): VideoRAM: 8192 kByte
My theory is that I could eliminate the problem if I could also get 8192 kB of video RAM.
Any ideas?
