I would point out you have provided close to zero input on the precise nature of your problem (no errors, no timings) . You have also provided about zero information regarding your installation (try the results of inxi -Fxxxz or similar)
I do not see any errors nor any specific timing. For example when i move around the terminal window with my mouse, after a few seconds, or directly or after 10 seconds (nothing directly set) of moving it around it is shortly staying at the same position and then jumps to where the mouse should be.
As I am writing this I also notice issues with typings, as I type stuff and sometimes it is not typed in directly but is lagging for a second and then it is displayed.
Sorry for not directly giving that information.
Sorry but I am unsure how to run such diagnostics. However when doing free I see a total of 14920 and 435 used. I also enabled shared memory in UEFI because I read it somewhere, that’s where 1GB is.
I noticed that I have 3200 DDR4 memory in a up to DDR4-2933 board, however it shows up as 2133 in UEFI?
Try a liveusb and see if you get the same problem(s). Try manjaro xfce first. Then if things are still problematic, perhaps you should try something non-manjaro based to see if the problem is not distro specific. A good distro to try might be MXLinux ahs… if you do be certain to use the ahs version.
Then you probably have a hardware problem. You should contact your hardware manufacturer especially check their site for guidance on running hardware diagnostics.
I also ran windows on it and that worked fine, had no issues after installing graphics drivers. That’s why it has to be something linux system related.
Could be the hardware vendor is simply incompatible with new drivers. Given you have had the problem with both *buntu & manjaro who are good with their new driver support… You probably simply have to wait a year before things work. You can check to see if the hardware is Ubuntu certified.
May I suggest something simpler first? Run htop and Search (F3 or click F3 on the bottom of the screen) ‘baloo’, my laptop shows three instances of balooruner with 0% CPU usage, but I’ve had situations of the computer being totally unresponsive, and had to ‘Ctrl Alt F2’ to reboot the machine, and the culprit was baloo hogging all the resources indexing files.
I do not know what happened last year, but this problem disappeared. You can check the default settings at System Settings > Search > File Search, unselect ‘Enable File Search’ to see if this is the problem.
