I got a workaround for this to work; changed the mtrr table:
echo "disable=0">|/proc/mtrr echo "disable=1">|/proc/mtrr echo "disable=2">|/proc/mtrr echo "disable=3">|/proc/mtrr echo "disable=4">|/proc/mtrr echo "base=0x00000000 size=0x80000000 type=write-back" >|/proc/mtrr echo "base=0x80000000 size=0x40000000 type=write-back" >|/proc/mtrr echo "base=0xc0000000 size=0x10000000 type=write-back" >|/proc/mtrr echo "base=0x100000000 size=0x100000000 type=write-back" >|/proc/mtrr echo "base=0x200000000 size=0x20000000 type=write-back" >|/proc/mtrr echo "base=0x220000000 size=0x10000000 type=write-back" >|/proc/mtrr cat /proc/mtrr reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1 reg01: base=0x80000000 (2048MB), size=1024MB: write-back, count=1 reg02: base=0xc0000000 (3072MB), size= 256MB: write-back, count=1 reg03: base=0x100000000 (4096MB), size=4096MB: write-back, count=1 reg04: base=0x200000000 (8192MB), size= 512MB: write-back, count=1 reg05: base=0x220000000 (8704MB), size= 256MB: write-back, count=1 reg06: base=0xd0000000 (3328MB), size= 256MB: write-combining, count=1 made a file under init.d, called mtrr_bug_fix with the changes to the mtrr table made it executable: sudo chmod +x mtrr_bug_fix linked it to the rcS.d: cd /etc/rcS.d/ sudo ln -s ../init.d/mtrr_bub_fix S03mtrr_bug_fix rebooted, everything works fine now -- Xserver crash with fglrx driver https://bugs.launchpad.net/bugs/232141 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
