I installed F18. Was previously on F15.
Overall, am pleased with F18.
Have old hardware, 1G RAM. Was afraid to upgrade, but all is well.
I used KDE on F15. Still using KDE on F18.
One thing.
Similar to F15, my cursor disappeared several hours after I booted up.
I added the same fix I used in F15.
I added a file, that turns off HWCursor for the nouveau driver.
rsewill@localhost:~ <3:1> $ more
/etc/X11/xorg.conf.d/01-local-setup-mouse.conf
Section "Device"
Identifier "Configured Video Device"
Driver "nouveau"
Option "HWCursor" "off"
EndSection
rsewill@localhost:~ <3:2> $
This is an FYI because this solution appears to work for me.
If anyone has a better solution, or a more approved solution, please speak
up.
