[opensuse-support] latest snapshot - distorted screen on DELL XPS 13 9370
Hi *, my DELL XPS 13 9370 has a builtin Intel UHD Graphics 620 chip. After installing the latest Tumbleweed snapshot yesterday I get a completely distorted screen in KDE after login from sddm. The problem only occurs, when using xf86-video-intel, using the modesetting driver everything looks as expected. Two questions: 1. The latest snapshot updated libvulkan_intel-18.1.7 to libvulkan_intel-18.3.1. Can this be the culprit? 2. What in general is the best X11 driver for the 620 chip at the moment - intel or modesetting? And why? Thx! Bye. Michael. -- Michael Hirmke -- To unsubscribe, e-mail: opensuse-support+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-support+owner@opensuse.org

2. What in general is the best X11 driver for the 620 chip at the moment - intel or modesetting? And why?
IMO: modesetting Why 1: it's the only X driver I've used with any gpu that supports it since I discovered it at least two years ago Why 2: last official release of xf86-video-intel was more than 3.5 years ago: https://cgit.freedesktop.org/xorg/driver/xf86-video-intel/ Why 3: ISTR on the intel-gfx mailing list a while back seeing mention that primary focus by those paid by Intel for Linux driver work was on the modesetting driver Why 4: It's been the apparent default in Debian and other distros for quite some time: https://www.phoronix.com/forums/forum/linux-graphics-x-org-drivers/intel-lin... https://www.phoronix.com/forums/forum/linux-graphics-x-org-drivers/intel-lin... Why 5: I've seen nothing to explain why the foundational differences between the way the two work might suggest one or the other might be theoretically better of not better in practice Why 6: history in forums of gfx problems disappearing when xf86-video-intel is uninstalled Why 7: at least in theory, unnecessary to switch X configuration to use a different driver when a gfxcard is added to or removed from a PCIe slot in a motherboard with both Intel CPU and video output ports -- Evolution as taught in public schools is religion, not science.

Why 3: ISTR on the intel-gfx mailing list a while back seeing mention that primary focus by those paid by Intel for Linux driver work was on the modesetting driver
Why 4: It's been the apparent default in Debian and other distros for quite some time: https://www.phoronix.com/forums/forum/linux-graphics-x-org-driver s/intel-linux/886898-ubuntu-debian-abandon-intel-x-org-driver-for-most-hardwa re-moves-to-modesetting-ddx https://www.phoronix.com/forums/forum/linux-grap hics-x-org-drivers/intel-linux/923618-fedora-switching-away-from-intel-x-org- ddx-driver
Why 5: I've seen nothing to explain why the foundational differences between the way the two work might suggest one or the other might be theoretically better of not better in practice
Why 6: history in forums of gfx problems disappearing when xf86-video-intel is uninstalled

Hi again, Felix answered my second question in an elaborated way. Anyone who can answer my first question?
1. The latest snapshot updated libvulkan_intel-18.1.7 to libvulkan_intel-18.3.1. Can this be the culprit?
TIA. Bye. Michael. -- Michael Hirmke -- To unsubscribe, e-mail: opensuse-support+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-support+owner@opensuse.org

Educated guess: likely candidate. Those match the to and (long awaited) from Mesa versions announced in the 20181214 update. It may be interplay between mesa/vulkan and plasma and/or compositing. I took a Kaby Lake TW 20181112, locked Mesa, installed xf86-video-intel, dup'd, and IceWM worked fine. Then I unlocked Mesa, dup'd again, and IceWM still OK. But, my Kaby Lake is HD 630 on 1920x1200, not UHD 620 (on 3840 x 2160?). -- Evolution as taught in public schools is religion, not science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks!
