can you retry with some of the later F10 kernels/xorg-x11-drv-ati drivers? need to know if we are still seeing this issue. Created attachment 322243 [details]

The problem still exists. Pidgin + Firefox with two windows (5 + 8 tabs). Not sure if the hangs are shorter but seen many at least 3+ seconds. Hard to use almost to being unusable. nomodeset seems to still fix it all. Only tested not running F10 kernels for the normal use (ptrace Bug 468089). Sure thanks for the updates, though. Please test with the -88 kernel from koji to see if this still happens. Created attachment 322973 [details]

The problem still exists. Pidgin + Firefox with one window (3 tabs). Not sure if the hangs are shorter but seen many at least 6 seconds. Hard to use almost to being unusable. Sure thanks for the updates, though. glxtest FPS went 110 -> 121 (improvement).compared to kernel-2.6.25.10-86.fc9.x86_64 (the default nomodeset-like mode there). Looking at bug 471669 comment 8 -- Honzo, do you think you can decrease the number of your workspaces from 24 to some reasonable number (like 4) and test the speed? Maybe it is really about screwed up memory management or something like this, which has not been tested with so high number of workspaces. This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Problem still exists although it is acceptable now (only about 0.5sec delays). xorg-x11-drv-ati-6.9.0-63.fc10.x86_64 kernel-2.6.27.9-163.ptrace.fc10.x86_64 Driver "ati" Option "AccelMethod" "EXA" Option "DynamicClocks" "on" (no kernel option - therefore default modeset) It was working without any delays before on: kernel-2.6.27.9-157.ptrace.fc10.x86_64 nomodeset Driver "vesa" If it helps the delays problem is the same for Driver "radeonhd" as is for Driver "ati" That "vesa" still cures that. Tried after a while and the problem is no longer present with: xorg-x11-drv-ati-6.13.0-0.7.20091006git457646d73.fc12.x86_64 Comment 20 is invalid, I forgot I use nomodeset now, I will try it without it. Verified Comment 20 without nomodeset, on kernel-2.6.31.1-56.fc12.x86_64. |
Created attachment 320714 [details] xorg.conf Description of problem: After switching from F9 to F10 kernel I get up to 10 second lockups in X. IMO any larger memory transfers are terribly slow - switching vitrual desktops, switching larger windows etc. Version-Release number of selected component (if applicable): kernel-2.6.27-17.fc10.x86_64 How reproducible: Slow X is a longterm problem for any post-F9 Rawhide kernels. With kernel-2.6.27-17.fc10.x86_64 I tried it only once. Steps to Reproduce: 1. Boot with default kernel (without nomodeset). 2. 24 virtual desktops, all the windows fullscreen, gnome-terminals, Firefox + Pidgin being switched on one virtual desktop Actual results: It takes 2-10 second to switch them. Expected results: Immediate response. Additional info: Specifying `nomodeset' for kernel makes it run X perfectly - like F9 kernels. 1400x1050 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility X1400 (prog-if 00 [VGA controller]) Subsystem: Lenovo Thinkpad T60 model 2007 Flags: bus master, fast devsel, latency 0, IRQ 16 Memory at d8000000 (32-bit, prefetchable) [size=128M] I/O ports at 2000 [size=256] Memory at ee100000 (32-bit, non-prefetchable) [size=64K] [virtual] Expansion ROM at ee120000 [disabled] [size=128K] Capabilities: [50] Power Management version 2 Capabilities: [58] Express Legacy Endpoint, MSI 00 Capabilities: [80] Message Signalled Interrupts: Mask- 64bit+ Count=1/1 Enable- Kernel modules: radeon Lenovo T60 (Red Hat machine), 3GB RAM Tried many xorg.conf changes with no success before.
