[SOLVED] intel graphics + compiz = white screen

everything worked ok this morning, now it does not. havent done updates. i just decided i could try KMS, so i followed this post: http://bbs.archlinux.org/viewtopic.php? … 65#p522665

during my test run of KMS, ive realized i could now disable "indirect rendering" for compiz. and everything worked ok. but, after being done with KMS (UXA is too buggy), rebooted with all changes undone, and now i get this error.

using compiz, i get a white screen with the black mouse pointer. xorg still works, since i run metacity --replace and everything works.

here's my xorg.conf device section

 Section "Device"
    Identifier  "Card0"
    Driver      "intel"
    VendorName  "Intel Corporation"
    BoardName   "Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller"
    BusID       "PCI:0:2:0"
    Option         "AccelMethod"    "EXA"
        Option      "MigrationHeuristic" "greedy"
        Option      "ExaNoComposite" "false"
    Option      "DRI"                    "True"
EndSection

ive searched the wiki, google, and under my bed for an answer and couldnt find any sad

its actually 'working' since rotating the cube kind of works (white cube, and slow), but cant seem to find the answer for this problem

Re: [SOLVED] intel graphics + compiz = white screen

I'm using xf86-video-ati, and had the same problem with "white compiz", xvinfo, "mplayer -vo xv" etc not working.
The solution? Re-install xorg-server big_smile

I hope this works for you, I spent hours banging my head against the wall. If not, I'd check Xorg log for any errors

by reinstall you mean:

pacman -S xorg-server

??

done that, no go.

now ive realized glxgears under metacity, dropped from ~900 to ~150ish frames per second. there is something really wrong with what happened today while setting up KMS im going to ping the guy that posted that howto...since it appears hes having the same performance issues.

EDIT: now i found out i had xf86-video-intel 2.6.3-3 installed instead of what i used to have (2.6.99.902-1) which i forced from my pkg cache....i restarted xorg and still nothing....

EDIT2: tried with xf86-video-intel-legacy and xf86-video-intel-newest from aur, both experience the same problem.

EDIT3: been looing into this further and this is what i get from xorg's log:

(EE) [drm] drmOpen failed.
(EE) intel(0): [dri] DRIScreenInit failed. Disabling DRI.

and ive realized the module i915 isnt being loaded: this error

ATAL: Error inserting i915 (/lib/modules/2.6.29-ARCH/kernel/drivers/gpu/drm/i915/i915.ko): Unknown symbol in module, or unknown parameter (see dmesg)

and its dmesg error:

mtrr: no MTRR for d0000000,10000000 found
i915: Unknown parameter `#'
i915: Unknown parameter `#'
mtrr: no MTRR for d0000000,10000000 found
i915: Unknown parameter `#'
i915: Unknown parameter `#'

im lost sad

EDIT4:
finally, i dont know why this started happening, but forcing to load the modules intel_agp drm and i915 in mkinitcpio.conf fixed it. im going to mark this thread as solved.
