This may be better filed under another component but was advised to initially file this under the kernel, however it maybe Xorg related.... hard to be 100% as I am not a dev, just a lowly user ;) Fedora Core 14 32 bit Linux 2.6.35.13-91.fc14.i686 #1 SMP ATI Binary drivers 11.5 installed using automatic mode of the installer Quad Core 9560 ATI HD5700 PCI-E Asus P5B-Pro M/B I do not think this occurred on previous kernels. When I move the pointer to the bottom right corner of the screen the mouse pointer stutters and temporary freezes for a second or so. Makes no difference what is on screen in that corner, be it the gnome bar or just the wall paper. I can eventually move the mouse pointer away from the corner and it is then ok. No problems at any other part of the screen or when windows are moved in the corner as long as the mouse pointer itself does not enter the very bottom right. I have noticed under system monitor that then when the mouse freezes the load momentarily increases. Also under active processes kondemand appears or more usually xorg (root) with >100% cpu load for the moment of mouse freeze.
Strange as it sounds we really suspect fglrx might be in fault here. Please, are you able to reproduce this issue with open source drivers from xorg-x11-drv-ati (don't after uninstalling fglrx to check integrity of packages with rpm -Va xorg-x11\* mesa\* ). Thank you
Yes, I thought this also, maybe the ATI driver at fault. BTW...This is what I get with the ATI driver installed. rpm -Va xorg-x11\* mesa\* ....L.... /usr/lib/xorg/modules/extensions/libglx.so ....L.... /usr/lib/libGL.so.1 ....L.... /usr/lib/libGL.so.1.2 When I un-install the binary package I'll retest the above command. What I normally do before a kernel update is uninstall the ATI driver, yum reinstall mesa-libGL, update kernel and reboot into the new kernel. Then re-install the ATI binary drivers. I have a fault with the open source ati driver on the login screen with a corrupt background, from cold start this is a random speckled colour screen and from a reboot the background is just like a capture from the previous session at logout.... as though a frame buffer is not being cleared or used correctly. That is why I use the closed driver, plus the fact the closed driver de-clocks considerably at desktop rather than running the vid card at full speed raising its temp another 20 deg just like in a game under windows. No problems under win7 as I dual boot for gaming.
Ok, running the open source driver I get the following with the rpm command. rpm -Va xorg-x11\* mesa\* S.5....T. /usr/lib/xorg/modules/extensions/libglx.so Confirmed the mouse fault has gone so it must be an issue or compatibility problem with 11.5 driver from ATI and this kernel.
Back on the closed driver 11.4 installed via rpmfusion (akmod-catalyst). No problems with the mouse so this is either an ATI 11.5 bug or a problem with the binary package. Maybe worth reporting to ATI ???? BTW amdcccle reports the previous version 11.5 still installed under its gui info screen but 11.4 is reported with yum. deleted amdpcsdb under /etc/ati but it gets recreated from somewhere else on next amdcccle run and still shows the wrong version but no big deal. Close this bug report.

Yes, but I am afraid you have to file the bug report. > Close this bug report. I am really sorry we cannot help you more.
Sent feedback report with ATI for this bug.
