I’ve just switched to Netrunner, so please excuse me if I’m ignorant about how to figure out stuff on this system
I’ve installed Netrunner Rolling 2015.11 on my i915-based Zenbook Prime. This worked fine, but as soon as I do
sudo pacman -Syu
to upgrade the system, my X configuration breaks. I can boot into the desktop manager (sddm, right?), but as soon as I enter my password and hit ENTER, X will crash and drop me into the login screen again. From the previous session’s Xorg.0.log, I can see that I’m hitting an instance of the same bug that has been reported for Fedora before:
I’ve tried using mhwd to switch to the pure intel driver, to no avail. I was able to restore working X funktionality by changing:
in the Device Section of my Xorg config. However, this way I loose AIGLX / Composite and probably any kind of hardware accel, too.
Has anybody seen this kind of issue before? Maybe even know a fix?
How can I figure out which package’s upgrade caused this issue? Can I do some trial-and-error downgrading to bisect the offending change?
