Meaning, I didn't use rpmfusion or another repository. I am using the Oxygen Style as well as the Oxygen Theme and I've no performance issues whatsoever.

This will cause the boot to hang with an unknown parameter warning from nvidia / LSB. I apparently had forgotten to check the file back out of version control before rebooting last time. I recovered by doing Alt-Ctrl-F3, getting to a console, removing the parameter, and rebooting.

Fedora by default uses gradients in their themes. There were three solutions: a) Downgrade Cairo b) Patch Cairo c) Don't run themes with gradients Cairo was released with a buggy gradients patch, with the caveat that it would NOT be carried over to Fedora 15. This fixed the performance problems in Fedora 14, but now we're running Fedora 15. You can really see the difference if you have run GtKPerf on Fedora 14, then run it on Fedora 15. The text input is three times slower on Fedora 15. After trolling the NVidia forums, I found a solution that works for me. a) Run a 270 or greater driver (required for xserver 1.10) b) create a file called nvidia in /etc/modprobe.d c) add the following: options nvidia AccelerateTrapezoids=0 d) ln -s /etc/modprobe.d/nvidia.conf nvidia (so boot doesn't complain) e) reboot After doing this, GTKPerf performed slightly better than it did on Fedora 14. See if this helps you out. . . . just my two cents. /mde/ -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
KDE Laggy in Fresh F15

Re: KDE Laggy in Fresh F15
I have not installed any software not in Fedora's repository (no nvidia drivers). Yeah, I guess you are hitting nouveau bugs here. So why don't you simply install the nvidia drivers? Do the problems also happen with desktop effects disabled? - Clemens -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
Re: KDE Laggy in Fresh F15
From: Clemens Eissererlinuxhi...@gmail.com I have not installed any software not in Fedora's repository (no nvidia drivers). Yeah, I guess you are hitting nouveau bugs here. So why don't you simply install the nvidia drivers? Do the problems also happen with desktop effects disabled? - Clemens I'd like to at least try to isolate the bugs and report them first. If everybody immediately switches to the proprietary drivers then the nouveau drivers and/or KDE will never improve. I'll eventually try the nvidia drivers so I can be sure it's a KDE/nouveau issue but first if anybody can say try this mesa patch, strace this or gdb that I'll do it. KDE automatically disables desktop effects. I can not disable them because I can not enable them... Well I could also disable the performance checks but I don't want KDE any slower. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
