fglrx on ubuntu 8.04 64 bit doesn't work

Asked by gnuser

I tried to install the new ATI driver 8.3/8.4 on Ubuntu 8.04 64 bit in many different ways, but never works and gets stuck with a black screen, with no error message. (32 bit version works regularly!!!)

My system:
p5k-e with 8 GB RAM
and ASUS 3850 512 MB

Nothing else is strange apart from these log lines:

kernel log: [fglrx] Maximum main memory to use for locked dma buffers: 7766 MBytes.
kernel log: [fglrx] ASYNCIO init succeed!
kernel log: [fglrx] PAT is enabled successfully!
kernel log: [fglrx] module loaded - fglrx 8.47.3 [Feb 25 2008] on minor 0

kernel log: mtrr: type mismatch for d0000000,10000000 old: write-back new: write-combining

daemon log: gdm[5828]: GLib-CRITICAL: g_key_file_get_string: assertion `key_file != NULL' failed
daemon log: gdm[5828]: GLib-CRITICAL: g_key_file_free: assertion `key_file != NULL' failed

any suggestions?

TIA

You can disable memory mapping in the bios (however, you'll end up with significantly less memory available for the system).

no changes by disabling memory mapping in the bios...

my /proc/mtrr on Ubuntu 8.04 - 32 bit - (fglrx works):
reg01: base=0xe0000000 (3584MB), size= 512MB: uncachable, count=1
reg02: base=0x00000000 ( 0MB), size=8192MB: write-back, count=1
reg03: base=0x200000000 (8192MB), size= 512MB: write-back, count=1
reg04: base=0x220000000 (8704MB), size= 256MB: write-back, count=1

my /proc/mtrr on Ubuntu 8.04 - 64 bit - *updated* (fglrx doesn't work):
reg00: base=0xd0000000 (3328MB), size= 256MB: uncachable, count=1
reg01: base=0xe0000000 (3584MB), size= 512MB: uncachable, count=1
reg02: base=0x00000000 ( 0MB), size=8192MB: write-back, count=1
reg03: base=0x200000000 (8192MB), size= 512MB: write-back, count=1
reg04: base=0x220000000 (8704MB), size= 256MB: write-back, count=1

TIA

Hmm. I've submitted either this problem (or a similar problem) as bug (https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.24/+bug/224404). Perhaps you could add some information regarding your situation.

You are right: same situation, almost same hw (my hw 3850 vs 3870 and 8 GB vs 4 GB) and and it's a bug of 64 bit version for me too. In fact, I tried other 64 bit distributions with kernel 2.6.24 with same results: fglrx doesn't work. It works on the 32 bit version instead...

What kind of information do you need? Logs ? Hw specs?....

I think you should add your logs (dmesg, Xorg.0.log, ) and hardware specs (Motherboard, CPU, Memory, Graphics Card) to the bug report. My guess the problem lies with the kernel being given the wrong information from the BIOS.
