For the last few months (that is, several Tumbleweed updates) I occasionally get lock-ups when I switch between the GUI display and the CTRL-ALT-Fn consoles. Usually the screen will switch to the console, which is typically showing a login prompt, but thereafter it is completely unresponsive to keystrokes. So I can’t switch back with CTRL-ALT-F7. The only way out of this seems to be to switch off/on.
It’s not something I need to do very often, but it’s annoying when it happens. Is this a known issue? Has anyone else seen it? I would say it hangs perhaps once in 10 times using CTRL-ALT-Fn.
I’m guessing this is a kernel/driver issue? My latest uname -a is “4.1.6-3-desktop #1 SMP PREEMPT Fri Aug 28 10:59:34 UTC 2015 (d867e86) i686 i686 i386 GNU/Linux”
I saw something similar in 13.2 about a year ago, then it was determined that the i915.ko graphics driver had problems with my graphics chip.
That bug was fixed by Intel a few weeks later. Never experienced that in Tumbleweed, but it might depend on which chip you use.
Another hint, if you are using Gnome, GDM had some problems with wayland, disabling wayland in /etc/gdm/custom.conf fixed them.
I see you declare kernel 4.1.6-3-desktop? So you are several updates behind the current TW?
If you installed some new package recently (without first doing a “zypper dup”) you are likely to have broken your system.
I usually use KDE and I haven’t installed anything that I can think of recently - I just do zypper dups.
I’ll try another Tumbleweed update sometime, but the problem has existed in the last two updates I’ve done (which is probably six or eight months). I really just wanted to know whether anyone else had experienced this.
I decided to take the Leap and did a “dup” upgrade last night. As far as I can tell, the problem seems to be sorted, although it was intermittent anyway. But hopefully, as you say, I’d somehow managed to break the system before and the update fixed it. Fingers crossed
