Remove that extra funcy stuff and see if it helps. - now you can look at config issues - do you utilize any outside filter/proxy, like squid ? - do you config proxy in firefox ? - take a look at config via menu - take a look at config via url about:config Start with filter like ipv6 (you can turn it off/on and see the effect) Btw, that was once a cause of identical firefox/chromium problem in the past ! about:config network.dns.disableIPv6 TRUE Continue with filter like dns, and so on. Remember to restart firefox if you change config (just in case, to have it take effect). - install other browser like Opera for testing and see if the problem persists. Jurek

F13 No Sound, No CDROM, K3B broken
by John Wendel 02 Jul '10

02 Jul '10

Just installed F13 X86-64 from the KDE live CD, had a few problems. [1] No sound - Pulse mixer shows no sound hardware. Fixed by changing permissions on /dev/snd/*. I thought console-kit was supposed to handle this. [2] No cdrom - Same problem, permissions on /dev/sr0. [3] K3B doesn't see the CD-DVD drive, wants to use HAL to detect the CD-DVD drive. I thought HAL was gone. Any clues would be appreciated. Thanks, John Wendel

qemu-kvm Trying to "Write" to a cdrom/sr0 ?? , Why?
by Jim 02 Jul '10

02 Jul '10

FC13 Selinux is in "permissive" mode Why would qemu-kvm try to "Write" to a cdrom, instead of "Read" ? Summary: SELinux is preventing /usr/bin/qemu-kvm "write" access on sr0. Detailed Description: SELinux denied access requested by qemu-kvm. It is not expected that this access is required by qemu-kvm and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug report.

preupgrade isn't efficient
by Martín Marqués 02 Jul '10

02 Jul '10

I'm doing a preupgrade from F12 to F13. yesterday I stopped preupgrade and started it again today. For my surprise preupgrade restarted downloading the installation images, which, with my slow connection, makes me loose more then 1/2 an hour only downloading the images. The question is, why does it download the installation images each time I start preupgrade again? -- Martín Marqués select 'martin.marques' || '@' || 'gmail.com' DBA, Programador, Administrador

Help with InstallMedia repo (it just refuses to go away)
by JD 02 Jul '10

02 Jul '10

$ sudo yum -y install parted Loaded plugins: refresh-packagekit Error: Cannot retrieve repository metadata (repomd.xml) for repository: InstallMedia. Please verify its path and try again I edited: sudo vi /etc/yum.repos.d/packagekit-media.repo and set enabled-0 It worked fine for one update session. Next update, problem comes back again. Why is it being clobbered with a new packagekit-media.repo ? Is there a conf file I can edit to permanently disable this repo?

ati catalyst workaround for fedora13
by nux＠li.nux.ro 01 Jul '10

01 Jul '10

Hello there, Does anyone know if there is a workaround for running the ati fglrx drivers on fedora 13 or how difficult it would be to port fedora 12's xorg to f13? For fedora 12 there is this: http://www.phoronix.com/forums/showthread.php?t=22884 And it works (thanks Steffen Seeger for the effort!), but I'm now on fedora 13 and laptop gets too hot with the experimental mesa drivers (altough performance wise they are decentish). Thanks! -- Nux! www.nux.ro
