[SOLVED] Can't launch Xorg as a regular user

mqrris · 06-08-2021, 03:13 PM

startx outputs this:

Code:

xf86Enable IOPorts: failed to set IOPL for I/O (Operation not permitted)

I tried this:
1.

Code:

sudo chmod u+s /usr/bin/xinit

2. I changed settings in Xwrapper.config to

Code:

allowed_users=anybody
needs_root_rights=yes

3. Reinstalled xorg and drivers for it a couple times.

Here is my logs:
Xorg.0.log: https://pastebin.com/JT7EJidA
lspci -k output: https://pastebin.com/tyFvWBq7

Do you have an xinitrc file? If so, what's it look like?

This may help: https://wiki.debian.org/Xorg

Why did you think that this was going to help?
What and where is the latter file?
I wouldn't mess around (esp. in system directories) unless I knew 100% why.
Are you able to undo these changes, now that they didn't help?

FWIW, your Xorg log shows that Xorg starts and imnmediately ends again. I only glanced, but nothing jumped out at me. This could be because it doesn't know what window manager (or DE session) to start.
Have a look at your distro's wiki, chapter Xorg.

try to use direct command xinit -e xterm - it opens root window with one instance of xterm. There is no wm running - there will be no window borders.

I executed

Code:

xinit -e xterm

And a new error appears, maybe it is the core of the problem. I remember how easy it was to solve such thing on gentoo, I'd just put in suid USE flag, and then recompile xorg, and it worked like a charm.

I am guessing /dev/tty0 is just console you are working now on. I think tty command can tell you - maybe try to open another virtual console - switch to that opened console and issue the same comman xinit -e xterm. Maybe Xserver by default is set to run on /dev/tty0. I am guessing of course. Switch to /dev/tty1.

Yeah I tried that right away, output is the same.

Perhaps it is security policy. Tried run as root?

This is the errors in the .local/share/xorg/Xorg.0.log when I run startx or xinit or xinit -e xterm as user

Code:

[   320.303] (EE) 
[   320.303] (EE) xf86OpenConsole: Cannot open virtual console 2 (Permission denied)
[   320.303] (EE) 
[   320.303] (EE) 
[   320.303] (EE) Please also check the log file at "/home/mqrris/.local/share/xorg/Xorg.0.log" for additional information.
[   320.303] (EE) 
[   320.303] (EE) Server terminated with error (1). Closing log file.

Xsession-errors if it's somewhat relevant.

Also, I executed xinit -e xterm as root and it didn't go well.
But just xinit worked and startx works as well, it even got me into dwm.

So you know that it is about limited uses permission. Perhaps making user a member of some group is needed to run xinit?

I recently boot into my Debian installation and the errors were gone, but startx still does not work as regular user. If I execute xinit there will be errors with the privilege restrictions. But I have Xwrapper that does provide xorg with roots rights if needed.
I'm quite confused, don't know where the problem rooted.

UPD: I issued startx -e xterm and it worked, thanks for your support.
