screen and mouse slow/lagging

English Hardware
1

I have a Shuttle DX30 mini desktop with Opensuse Leap 42.3 installed.
The graphic card is (according to hwinf) Intel and the i915 driver is in use.
However I experience slow mouse response/freezing and slow screen behavior, not constantly.
Windows is also installed in a dual boot mode, because I need access to some GPS software, that is not available in Opensuse. There is no issues in Windows.
I wonder what to do about it?

More specific graphics hardware details might be useful…

/usr/sbin/hwinfo --gfxcard

Which Desktop environment are you using?

Thanks! I am using KDE stock version that comes with Leap.

Ok, and while waiting for others to advise further please share your Xorg log just in case it provides some additional useful info. It’s a lengthy file, so best to upload it to https://paste.opensuse.org/ (set a sensible ‘Delete After’ period) and post the link that it generates here.

Here’s a Leap thread discussing similar behaviour for some Intel chipsets. A Leap 42.2 thread, but I think it may still be relevant here

I have tried the “uxi” option mentioned in the referred tread with no luck. Actually the boot process was extremely slow.
I have pasted my Xorg.log here: https://paste.opensuse.org/96012737
I hope it helps clarifying the problem. The last lines of the log tells that communication with the mouse/keyboard is not too well, but I am like one meter away from the adapter… so. Interference with other wireless devices?
On the other hand the keyboard works - slow but it does not skip characters. So I still think its a graphics/plasma prob.

Ah, so a wireless mouse and keyboard? Or just the mouse?

I have seen this tread and have removed the drm-kmp kernel without success. I have researched further into the issue and may think that is related to these error messages at boot time (photo): Dropbox - 20180124_202829.jpg - Simplify your life
Seems like something goes wrong with loading the i915 driver.
The processor is an Intel Apollo Lake J3355 CPU Processor, and next I will try to update bios and drivers via Windows.
I’ll report back the results.

I can add that audio playback also is hanging/freezing occasionally so it might be a cpu (microcode) issue or the GPU hangs causing overload at the system (just guessing/fishing)
For the graphics I found this info: https://wiki.archlinux.org/index.php/Intel_graphics#Enable_GuC_.2F_HuC_firmware_loadin

I have mailed Shuttle Computer in order to get instructions to update BIOS and CPU microcode.
I also extracted this from dmesg:
