 |
|
My laptop works fine after an update and a reboot, but after a week every X App I try to launch says this:
| Code: | ~ $ x2goclient &
[1] 11175
~ $ Authorization required, but no authorization protocol specified
qt.qpa.xcb: could not connect to display :0
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: minimal, offscreen, vnc, wayland-egl, wayland, xcb.
[1]+ Aborted x2goclient |
I have two other similarly configured machines and they don't have this issue.
Any ideas?
I'm off to reboot which fixes the issue.

look through dmesg for segfaults or other failures, i.e.
| Code: | | dmesg -T | tail 200 |
Also, explore your syslog.

I did this once before and I think it was a RadeonGPU crash, but I will do it again. Talk to you in a week.

Is your system hostname constant? I have seen some people with this problem when they let a DHCP client rename their machine.
Does restarting X, without rebooting, fix this once it happens? Is your xauth data the same between when it works and when it fails? |

I'm pretty sure I'm setting the hostname the normal gentoo way:
| Code: | cat /etc/conf.d/hostname
# Hostname fallback if /etc/hostname does not exist
hostname="lenny" |
But I just noticed the fallback comment. Let me google it.
Okay, so apparently I did not know about echo hostname > /etc/hostname except on my most recent install. The mediaPC is okay.
The server reports it's hostname properly, although /etc/hostname was missing:
| Code: | hostname -a
server localhost |
But for this laptop, even though I wrote to the /etc/hostname file, I'm getting this:
| Code: | hostname -a
hostname: Unknown host |
Ah! but plain hostname works! hostname -a doesn't work as above, but hostname does:
WTH?
Now that /etc/hostname exists, let me reboot again... I'll let you know what happens.

I hadn't filled in my /etc/hosts file with the name of localhost.
Or I did and it got overwritten when I did a dispatch-conf poorly.
Anyway, hostname -a works now.
Thanks for the clue, Hu! I really appreciate it.
If my laptop lasts until next update (two weeks from now) I'll let you know. If it doesn't last, you'll know sooner.

THANKS HU!
It looks like this was the source of the problem and everything is fixed!

| That is good to see. The explanation was not quite what I expected, but I am pleased that my question led you to a solution. |
