messy desktop effects on Thinkpad R40

[michust]

On Feisty Fawn herd 5.
After enabling desktop effects, only ca.1280x1050 on the 1400x1050 display are shown correctly. The rest is accessible for the mouse but messy for windows.
After reset X or reboot all panels are blank and no way to add something to it.

Your max texture size is smaller than your screen resolution, not a compiz bug. What video card do you have?

radeontool tells the following:

01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility
M7 LW [Radeon Mobility 7500] (prog-if 00 [VGA])
        Subsystem: IBM Unknown device 0527

devsel, latency 66, IRQ 11
        Memory at e8000000 (32-bit, prefetchable) [size=128M]
        I/O ports at 3000 [size=256]
        Memory at d0100000 (32-bit, non-prefetchable) [size=64K]
Radeon found. Base control address is d0100000.

If I remember correctly there is a way to increase the max texture size but I don't know if this should be rejected as a hardware limitation or not. Reassigning to the ati driver.

You can create /etc/drirc file with the following contents:
<option name="allow_large_textures" value="2" />

However, it's most probable your graphics card does not enough video RAM to handle the multiple large textures anyway.

Since the updates from the last days (2007-04-01) it runs.
little bit slow, but ok

thanks for help.

Ok, marking as fixed then! The slowness is probably because the 3D desktop has to use system memory partially, "swapping" between the Video RAM and system RAM.

Hi, I made the duplicate Bug 103300

the fix

worked right away, I didn't even have to restart X. Thanks so much Travis and Timo!

This is still a problem in gutsy (drirc must be modified in order to handle compiz)
