A Superuser issure


Hi Folks,

I am using Linux distributed from Scientific Linux version 7.9.

I was in a superuser mode with a command prompt "#", I tried to switch to "$" prompt, but after I click the upper right corner in the GUI to change I got a screen in the attachment.

Could anyone tell me how can I go back to normal GUI ?


Thanks in advance.

Not really sure what you are talking about when you say "you were in superuser mode and you're trying switch to a "$" prompt". It's hard to imagine you would be getting what are clearly error messages from the Intel sound driver in your kernel log simply by trying to change the look of the prompt, and/or just by running as the superuser/root (which you should NOT be doing in the first place unless you absolutely NEED TO).

In any case, it looks like some sort of bug to me. From my research, it seems you might be able to add a kernel parameter to silence those messages in your kernel log.

But we should first try and get a better understanding of your problem, if you login as a normal user;

* Does your graphical environment actually load up at all, yes or no?
* If it does load up, exactly what is the problem past the messages you are seeing in your kernel log?
* Can you actually play any audio on your machine?

There is a bug in the kernel/driver snd_hda_intel (driver for an audio device).
Your action is not directly related but might indirectly trigger it.
Workarounds:
reboot with an older kernel
install kernel/driver updates
