[mpeters@gourmet ~]$ cat /proc/cpuinfo processor : 0 cpu : 740/750 temperature : 44 C (uncalibrated) clock : 450MHz revision : 131.0 (pvr 0008 8300) bogomips : 897.02 machine : PowerMac2,2 motherboard : PowerMac2,2 MacRISC2 MacRISC Power Macintosh detected as : 66 (iMac FireWire) pmac flags : 00000014 L2 cache : 512K unified memory : 384MB pmac-generation : NewWorld Just installed todays rawhide. iMac kept rebooting during rawhide install - at random places but always while downloading, doing a minimal install got it to install all the way. Machine did not randomly reboot in OS 9.2 Then - yum groupinstall "X Window System" "GNOME Desktop Environment" "GNOME Software Development" went fine without a hitch. I'm currently booting into run level 3 - X11 starts rather slowly (via startx) and ssh'ing in and running top shows it using an insane amount of the CPU - between 94 and 99. It will eventually suddenly drop and I can move the mouse etc. but as soon as I click something, anything, it gets bogged down again and the usage of X in top skyrockets. my xorg.conf and Xorg.0.log file can be viewed here: http://mpeters.us/imac_xorg/ Anyone know what's going on? I'm tempted to see if it works better via remote xdmcp - but not sure I want to enable gdm if it eats the CPU whenever it does anything X related.
