Skylake Graphics, Intel HD 530

I have laptop with integrated intel graphics and some problems.
Acer VN7 592, i7 6700hq, NVIDIA 960m discrete card

Problems: gpu acceleration working bad, I have artefacts (glitches around text), sometimes tearing.

https://wiki.archlinux.org/index.php/in … ke_support
I tried i915.enable_rc6=0 - not working for me (+ I don't like this solution), artefacts and sometimes tearing.

When I use firefox with force GPU acceleration, it's unstable and freezing.

I don't want disable 2d acceleration...

I just switched to nvidia prime (use only discrete card). And all working nice and much faster (I mean apps like firefox, chrome). I like this variant, but laptop hot when I use only nvidia...

Simple question does Intel 530 GPU on laptop usable now in linux?

Re: Skylake Graphics, Intel HD 530

In terminal: glxinfo | grep rendering
What's the output when using IGP?

I tried DRI 2, tearing gone, but I still see glitches around text. And I think after suspend / wake I can see video tearing again.

Re: Skylake Graphics, Intel HD 530

I have an HD520 using the modesetting driver and it just works without problems.

When I use firefox with force GPU acceleration, it's unstable and freezing.

Maybe forcing something is not a good idea. Here I don't force anything and it works fine even if it says basic compositing. Regarding the artifacts you would have to either take a printscreen(1) or a photo to show what you mean, regarding tearing that is expected, the "fix" is to use a compositor, alternatively you have to use the xf86-video-intel driver and create a custom xorg configuration file to activate the tearfree option. Be aware that using the xf86-video-intel driver can result in other problems so check which one works better for you.

(1) If the problem shows up in a printscreen it's most probably not a driver problem.

Re: Skylake Graphics, Intel HD 530

I tried with/without compositor (compton glx)
with/without force acceleration (firefox)

Had problems

PrtScreen - hard to catch moment I'll try.

But I set now DRI2 in xorg.conf and dosn't see problems (I'm sure it was... with DRI2)

Re: Skylake Graphics, Intel HD 530

Same stuff in apps like krita

Note: I use 288 DPI (4k display)

(1) If the problem shows up in a printscreen it's most probably not a driver problem.

Why with nvidia driver all works correctly?

Compositor - It can help with video tearing? (I had same problems in ubuntu / nvidia driver before xorg update, as I remember here integrated compositor and same thing was with compton/arch. After xorg / nvidia drivers update, I doesn't see video tearining with nvidia).

With DRI2 - no video tearing, only glitches around text.

UPDATE:
combination xf86-video-intel
                     DRI2
                     compton + glx

looks like working for me (not 100% sure now)

Re: Skylake Graphics, Intel HD 530

Which DE are you using now?
I just noticed Gnome with Wayland session gives a bad performance on graphics,
frames dropped like crazy when watching Youtube in Chrome, with Xorg, everything is smooth as it should be.

BTW, I'm using HD 630 with i3 7100.

I use x.org and i3wm.

Looks like composite manager + correct config fix my issues. I had same config before, but it not worked. Maybe kernel/xorg update fixed something.

Sometimes still see glitches (screenshot above)... Discrete gpu disabled [acpi_call]. Compton is running.

I don't know what it can be...
