After couple of updates compiz started crashing and xrandr stopped recognizing settings properly. I used xorg.conf for a while only as a work around. Now after couple of recent udpates, I found that it works fine again with no xorg.conf except I need to xrandr -s 0 to restore settings for my display and I had to edit settings for compiz to make it work properly again. <TABLE CELLSPACING="0" CELLPADDING="0" WIDTH="100%"> <TR> <TD> <PRE> -- -------------------------------------------------------------- Grzegorz Witkowski :: <A HREF="mailto:geslinux@gmail.com">geslinux@gmail.com</A> :Gadu-Gadu: 5942122 :ICQ: 427096157 :Skype: gesirl -------------------------------------------------------------- 01000111 01100101 01110011 01100011 01100001 01110000 01100101 <A HREF="http://counter.li.org">http://counter.li.org</A> #239224 Registration 2001-10-29 07:19:32 -= GNU/Linux - The Experience of Freedom =- </PRE> </TD> </TR> </TABLE> -----Original Message----- From: Skunk Worx <<A HREF="mailto:Skunk%20Worx%20%3cskunkworx@verizon.net%3e">skunkworx@verizon.net</A>> Reply-to: "Community assistance, encouragement, and advice for using Fedora." <fedora-list@redhat.com> To: For users of Fedora Core releases <<A HREF="mailto:For%20users%20of%20Fedora%20Core%20releases%20%3cfedora-list@redhat.com%3e">fedora-list@redhat.com</A>> Subject: f12 updates kernel nomodeset option breaks radeon Date: Sun, 29 Nov 2009 16:27:59 -0800 <PRE> After updates today my radeon driver does not start properly if the kernel nomodeset option is used. The X log has a message : "Couldn't find valid PLL dividers" Good news though in other areas : --I can shell into the machine with ssh, it's not a hard crash. --If I set up the kernel with "rhgb quiet" and do not use the "nomodeset" option X starts up normally. --I no longer need an xorg.conf with "XAA" accel enabled to prevent X crashes. EXA seems to be working reliably now. (I previously reported that <A HREF="http://www.newegg.com">www.newegg.com</A> and wiki.centos.org were crashing X with EXA enabled.) EXA seems stable with kernel modesetting though...great!
