-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Yesterday afternoon I upgraded my laptop to Tumbleweed 20180116. I don't remember the Tumbleweed serial that I was on before then specifically, but my last upgrade day was Jan 8 of this year. Following the upgrade, after rebooting my laptop and logging into Plasma, I was greeted with a black screen with a mouse cursor. The weird thing is I could still hear my computer sounds in the background, and the mouse cursor would change shape based on what was underneath it. Eg., KGPG prompts for my password on login, and I could enter the password and hit enter and the mouse cursor would change appropriately. I could also (blindly) do alt+f2, type in konsole<enter>, type in screen<enter>, start a ping, and then resume that screen session from one of the virtual terminals. So it was as if KDE was running but hidden. I tried creating a new user account and trying to log into it (same issue,) so I knew that it wasn't a profile problem. So, I rebooted and tried to log in, and as soon as I did that, I did the following from a virtual terminal: journalctl > journalctl.txt dmesg > dmesg.txt Looking at the journalctl file, I saw this: Jan 18 14:14:28 caradhras.millikin.edu org.kde.kglobalaccel[5242]: libEGL warning: DRI2: failed to authenticate Jan 18 14:14:28 caradhras.millikin.edu org.kde.kglobalaccel[5242]: libEGL warning: DRI2: failed to open swrast (search paths /usr/lib64/dri) I did some poking around on Google, and saw references to problems with libmesa, so I decided to force-reinstall it just to be safe. As I was telling YaST to "upgrade" the various Mesa packages, as soon as I did that with the "Mesa" package, it auto-added two additional packages that weren't installed at the time - Mesa-dri and Mesa- gallium. After reinstalling all of the Mesa packages (including those two additional ones) and rebooting, all was back to normal again :) So it seems as if possibly that dependency wasn't set up correctly?
