All Icons are missing

i think youre the third user with this exact issue after updating to 5.26.2 … one solution was not installed the proper drivers, looks like thats not your case, second was downgrading plasma and the third just went away after some reboots…
you can check logs, maybe there will be some hint, but first do this:
kate /etc/environment
and add there this command:
QT_LOGGING_RULES='*=false'
this will disable useless logs, so that they are more readable, reboot and provide logs:
journalctl -b0 -p5 --no-pager

I have this exact same behavior after the last update. Will try to generate logging as indicated by the last post of this thread.

Update: this is the output of journalctl -b0 p5 --no-pager:

I hope someone (@brahma maybe?) can give me some hints what is going on. If you need more info please let me know.

theres nothing there in the logs unfortunately…
@ijskegel did you tried creating a test user and see if its affected too?

Yes, i have created a new test user. Performed a reboot. After first login with the new test user everything seems to be ok, but if I hover over an icon it disappears. After another reboot all icons are missing just as with the regular user.

I also notice font problems in some pop-up windows.

you can post output from:
inxi -G if you have the proper drivers, otherwise revert back if you have a timeshift backup, or downgrade only plasma:

you could also try switching to testing or even maybe unstable branch to see if its fixed there…

Thanks for your help. If only I had timeshift setup it would have saved me now. Lesson learned, if I get this problem fixed setting up timeshift will be the first thing I’m going to do.

I’m not at my laptop right now so can not provide the output of the inxi command. I’ll try to do that tomorrow.

In the meantime I’ll be reading the link about downgrading plasma.

Update: This is the output of the inxi -G command. I think I have the correct drivers installed, or would it be better to install the proprietary nvidia drivers i.o. the nouveau one?

Graphics:
  Device-1: Intel 2nd Generation Core Processor Family Integrated Graphics
    driver: i915 v: kernel
  Device-2: NVIDIA GF108M [GeForce GT 525M] driver: nouveau v: kernel
  Device-3: Quanta Laptop_Integrated_Webcam_2HDM type: USB driver: uvcvideo
  Display: x11 server: X.Org v: 21.1.4 driver: X: loaded: modesetting
    dri: crocus,nouveau gpu: i915,nouveau resolution: 1920x1080~60Hz
  API: OpenGL v: 3.3 Mesa 22.2.1 renderer: Mesa Intel HD Graphics 3000 (SNB
    GT2)

yes installing the proprietary drivers would be better, one user fixed his icon problem by installing the proper drivers…
but first add the ibt parameter to your kernel:
kate /etc/default/grub
and in this line: GRUB_CMDLINE_LINUX_DEFAULT inside the quotes add this parameter:
ibt=off
dont remove anything from there!, just add it to existing parameters, save the file, update grub:
sudo update-grub

now install the proper drivers:
sudo mhwd -a pci nonfree 0300

EDIT: you have the 390xx driver card, so do you have a optimus system?
post also output from:
mhwd -l -li

reboot and see if it helped

Note that my (very old) Dell laptop has a ‘optimus’ setup. In the past I installed bumblebee to get this setup working but since I do not use the machine for heavy graphics processing I decided that using only the internal (intel) graphics card was good enough.

I’m not sure if I can simply install the nonfree driver or if I need to do something else/more.

Wat does the ibt=off kernel parameter do?

yes heres my edit:

so yes, you are probably better off using nouveau instead of the 390/bumblebee/optimus … its a mess to set it up…
there are issues with nvidia if the ibt paramter is not set, it disables something in intel cpu, dont remember exactly …


you can try this also:

Tried the ibt=off kernel parameter but that did not fix it.

Before I switch to testing or maybe downgrading plasma I want to check one other thing. If I perform the actions as mentioned by @RUI_c plasma seems to crash and restart, after the restart everything is alright (until reboot).

Maybe the crash indicates what is wrong/missing on the system at that time. I will dig into the log files to see if I can find something.

P.S. @RUI_c apologies for hijacking your thread. Did you find a solution yet?

Not upset at all I just want to be of any help to anyone at all lol
No I have not found a fix for it other than what I have posted previously. I am going through the steps now from over night to see if my logs show anything different I will post shortly.

After more analysis I still could not find the cause of these problems.
I tried to upgrade from stable to testing but that did not help.
Finally I downgraded plasma and now everything is back to normal. See this topic for the procedure to downgrade to plasma-5.24.7-LTS.

Yes, see my post just above yours.

Unfortunately, I followed the steps but it did not fix it for me.
It kept me on 5.26.2

Did you get any errors or warnings?

No it all went smooth. (Or so I thought)

What steps did you actually take? Maybe I can spot a problem somewhere.
Ah wait, what pacman command did you use? On the solution in the linked page it states pacman -Syu but this should be pacman -Syuu (note the extra u).

Instead of “Next, log out of Plasma completely” I rebooted my laptop and when it showed the login screen I to a tty with Ctrl+Alt+F2 and logged in on the tty. After that I faced two minor issues:

  • I tried the sudo pacman -Syuu command but first that failed because I had no wireless internet connection. I had to plug in an ethernet cable.
  • After that the pacman command failed with “Error: failed to commit transaction (conflicting files)”. to fix that I used pacman -Syuu --overwrite '*'

Now my system is running fine again.

Yeah that is what I though I did put in the other u, but I repeated the process exactly as posted. I didn’t get any error messages. Everything said successful.

@RUI_c , sorry to hear that.

I remember one other issue I had. I had to remove the # ← new section comments from the /etc/pacman.conf file, they gave me errors.

I just checked my bashrc history and can confirm that I did not do anything else than written on the page I linked to earlier.

For me help only one solution
Downgrade kscreen and libkscreen to 5.25.1

i found this in other topic

Icons on the taskbar are not visible (drivers problem)

But i cant add url
