Computer freezing [twice]

[LaQuirrELL]

I am posting this under Applications, but it may not be an application issue.
opensuse Tumbleweed 20260318
KDE Plasma 6.62
Kernal 6.19.8-1-default (64-bit)
Graphics platform X11
Brave browser 1.88.134-1
Asus Z390-A m/board [new], CPU Intel i7-9700K, 32 gb Ram, integrated graphics, PSU 650 W [new].
NOTE: I am running Brave on openSuse on another computer and am not having any freezes on that one.
Twice now my computer has “frozen”, where my mouse will not respond. I have checked the mouse on other machines and it is OK [working].
I use Brave as a browser. The circumstances under which it froze are thus:
IN Brave:
1] opened a new tab
2] clicked on a browser shortcut [youtube]
3] clicked on a video in youtube
4] mouse became inoperative on any window that was open at the time
5] I could not even shutdown properly [i.e.] - click on Geco and click on Restart, I had to power down without exiting properly.
6] When I started up again everything was working normally. All my windows that I had open, reopened including Brave browser.
7] I was able to resume using Brave without anything freezing. The lapse between freezes was about 2 weeks and Brave acted normally throughout this time until the 2nd freeze.
Is there a log file that might tell me what may have caused this?
Or test program that would indicate a software or hardware problem, that I could run in the background?
I did google “Brave freezes” and one idea was that extensions should be disabled. I have no extensions in Brave. It also suggested disabling GPU, but as I am using “onboard” GPU I don’t think that is possible. Also suggested, was to “clear cache” which I had done between 1st and 2nd freezes.
I appreciate any help and suggestions. Thank you.

This is a longshot suggestion.

When we used TW, we occasionally had issues with our Chrome-based browsers, Brave being one of them.

There is a sub-directory named “GPUCache” that can be easily removed , which always fixed the oddity issues. It is simply a “cache” sub-dir, so doesn’t matter if cleared out.
(I have numerous bookmarks to those old posts for reference).

Anyway, simply run this command to find them - run it when logged in as your regular user account from its home sub-directory .

username@machine :~>  find ~/ -type d -name GPUCache

That will list all applications that are using a GPUCache sub-dir. Then move to that sub-dir of the app in question and delete its content.
.
One post as a reference:

Chromium and chromium based browsers (Vivaldi) not displaying content correctly

I had a similar issue recently with Chrome, Chrome Beta, Brave … no doubt Chromium will have it too. This fix works for me. For each affected app, I had to delete the associated GPUCache sub-directory. There is quite a few to delete, search for them like this find ~/ -type d -name GPUCache (in the users home directory) They can all be deleted in one fell swoop with: find ~/ -type d -name GPUCache -exec rm -rf {} + … but do it at your own risk. I actually renamed them to “GPUCache–ho…

@myswtest

find ~/ -type d -name GPUCache

Thank you for your help.
I did the command [although I needed to be root], followed the path it gave to the location of GPUCache for Brave Browser

The above picture shows what is in that file. Just to be clear: I am supposed to delete these files? Including the “index” ?

Something is rwong. You do NOT need to be the root user … everything in your /home/* is owned by your user account. (unless something is mis-configured).

Here I am logged in with my user account, and have run the command;

myuser@machine :~> find ~/ -type d -name GPUCache

myuser@machine/.config/BraveSoftware/Brave-Browser/Default/GPUCache
myuser@machine/.config/BraveSoftware/Brave-Browser-Beta/Default/GPUCache

myuser@machine/.local/share/kontact/QtWebEngine/Default/GPUCache
myuser@machine/.local/share/kioslave5/QtWebEngine/Default/GPUCache

myuser@machine :~>

And now to change to that sub-dir (as my user , NOT root) and clear its content:

myuser@machine :~> cd .config/BraveSoftware/Brave-Browser/Default/GPUCache
myuser@machine :~/.config/BraveSoftware/Brave-Browser/Default/GPUCache> ll

For some reason I could not run that original command unless I was root, but I have found GPUCache for Brave in
/.config/BraveSoftware/Brave-Browser/Default/GPUCache
in myuser [la] file. I will continue on with your example.
I do not think I will need root but will report back, either way.
Thank you for staying with it.
