I had a very trying day today trying to fix my -current install on my laptop. On April 19th(also my birthday \o/), Pat updated the kernel to 3.8.8. Well I didn’t reboot until yesterday but when I did X would only do 1024x768 and would not let me configure any monitors.
So the first thing I did was run X -configure, it returned with an error about the modesetting not being supported. The nex thing I attempted was
As you can see that didn’t work so well, so I checked dmesg and this is what that said:
1 2 3 4
Well crap. At this point I was pretty stuck so I went on irc and tried a long list of steps. I started with recompiling the 3.8.8 kernel, then I tried recompiling mesa and libdrm. Then I tried using insmod to load the radeon module and that didn’t work either.
So finally I had the bright idea of using the 3.4.x kernel because Pat has a config for it in testing/. So I compile that, reboot, voila, it works! I then try the 3.8.4 kernel and that works fine too. Finally after a long day of troubleshooting I was finally back at where I was with before Friday’s update.
So hopefully this will help someone out in the near future.
