[17:55] <furkan> tjaalton: on Ubuntu 15.04 i'm still having major problems with changing my desktop resolution
[17:55] <furkan> with both displays connected, when i change my screen resolution the desktop just turns black with only the mouse cursor visible
[17:55] <furkan> and it doesn't recover until i switch to a VT and restart lightdm
[17:56] <tjaalton> file a bug
[17:56] <tjaalton> try newer kernels
[17:57] <tjaalton> bisect if fixed
[17:57] <furkan> not a kernel issue, i've tried older and newer
[17:57] <furkan> i've also tried older and newer ddx
[17:57] <furkan> and mesa
[17:57] <furkan> i think that only leaves xorg and lightdm
[17:58] <tjaalton> lightdm has nothing to do with it
[17:58] <tjaalton> 04:52 < MrCooper> it's more likely a driver issue than an xserver issue
[17:58] <tjaalton> missed that one?
[17:59] <tjaalton> file a bug on bugs.freedesktop.org
[17:59] <furkan> driver doesn't seem to make a difference
[17:59] <tjaalton> uh
[17:59] <tjaalton> meaning it's not fixed yet
[17:59] <tjaalton> the driver is in kernel
[17:59] <tjaalton> that does modesetting
[17:59] <tjaalton> anyway, I'm off
[18:01] <furkan> tjaalton: issue isn't present in 14.04 though (i have a separate partition set up) so it seems like a regression
[18:01] <tjaalton> nothing new
[18:01] <tjaalton> things happen
[18:01] <tjaalton> file a bug
[18:02] <furkan> oh i'm not throwing blame anywhere, just looking for a way to narrow down what caused it
[18:02] <tjaalton> probably not finding it here I'm afraid :/
[18:03] <furkan> np, i'll file one on freedesktop and see if they have suggestions for debugging
[18:03] <furkan> i figure there's more  of a chance it'll get fixed if i do some debugging work, but i just don't know what to try
[18:04] <tjaalton> they'll know more
[19:34] <furkan> tjaalton: crazy as it may sound, it just occured to me to log out of unity, log in with xfce, and turns out i can change my desktop resolution without issue
[19:34] <furkan> does that indicate that it could be an issue with unity, or still a driver problem?
[19:40] <furkan> with unity, this is the error i get in Xorg.log, after changing the resolution: http://pastebin.com/ZW6akHf9
[19:40] <furkan> didn't notice it before, as it takes some time to come up
[20:08] <tjaalton> trying to run it non-root?
[20:09] <tjaalton> sounds like you broke it
[20:12] <furkan> non-root?
[20:12] <furkan> can't remember changing that
[20:13] <furkan> root      5926  7.2  0.8 654248 131936 tty7    Ssl+ 15:33   2:54 /usr/bin/X -core :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
[20:14] <furkan> seems to me like it's running as root?
[20:14] <tjaalton> seems so
[20:14] <tjaalton> try #radeon then
[20:16] <furkan> alright, i'll also make sure i can reproduce it from a live USB to make sure i didn't break anything..
