Unfortunately tv-out load detection is sometimes unreliable and there are only two display controllers. You should be able to work around it with something like: video=SVIDEO-1:d on the kernel command line. Look in look in /sys/class/drm to verify the connector name. Thanks for the workaround, but this worked fine prior to kernel 2.6.33.3-72.fc13. (In reply to comment #3) > Thanks for the workaround, but this worked fine prior to kernel > 2.6.33.3-72.fc13. It only worked by accident due to another bug that left always left tv-out disabled in certain cases. Is this still an issue with a newer driver/kernel? (In reply to comment #5) > Is this still an issue with a newer driver/kernel? Still the same with: 3.4.0-1.fc17.i686.PAE xorg-x11-drv-ati-6.14.4-6.20120602git930760942.fc17.i686 load detection is not always reliable. You'll have to boot with video=SVIDEO-1:d on the kernel command line in grub or disable s-video once you're in X. Most desktop environments should remember your settings and disable s-video in future sessions. |
