The newer kernels in the repo need to be built locally?

No, just add the repository via zypper and update from there, or download the packages manually and install them. -- You are receiving this mail because: You are on the CC list for the bug.

Try later i915-quickfix-kmp-default.rpm from http://donwload.opensuse.org/repositories/home:/tiwai:/bnc959245/

Oops, a typo there. The right URL is http://download.opensuse.org/repositories/home:/tiwai:/bnc959245/standard/ I refreshed the repo with more possible fix patches. It's being rebuilt again now. -- You are receiving this mail because: You are on the CC list for the bug.

For example, create /etc/X11/xorg.conf.d/60-intel.conf containing the following: Section "Device" Identifier "Default Device" Driver "intel" Option "AccelMethod" "UXA" EndSection This isn't always recommended, especially for new chips, but who knows... -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=959245 http://bugzilla.opensuse.org/show_bug.cgi?id=959245#c21 --- Comment #21 from Andreas Schleth --- OK, I still see the same type of failure. After logoff (not leaving tty7) there is a flicker when sddm switches to the greeter screen, the mouse pointer vanishes and if I move the mouse these color bars appear from the lower left edge (and some parts of the upper right hand corner are painted at the upper left). It is exactly the same behavior as if I switch to tty1 and back to tty7. The error message also is the same. (I do not exactly understand this S3/S4 thing.) Yesterday I did a few more experiments (all with the latest *ko and firmware): * change AccelMethod to SNA, UXA, off * Add option "DRI" "0" * fiddle with BIOS-Settings (HPET off/on), Graphics Memory increased to 1024M (was 256M), EUP off/on, EIST off/on, CPUID off/on, C-States off/on/auto All this did not change a thing. Then I tried the boot parameters nomodeset i915.modeset=0. This only resulted in not getting any X-session at all. As a side note: from a different partition I still can boot my old 13.2 (all updates until early December). There I do not have this problem at all. Well, sound and USB are not working, but X works well and switching to tty1 and back has no adverse effect. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=959245 http://bugzilla.opensuse.org/show_bug.cgi?id=959245#c23 --- Comment #23 from Andreas Schleth --- I did some more testing: First reset BIOS an enter the recommended parameters from c't Then tested suspend to RAM (Ruhezustand) S3? and suspend to disk (Tiefschlaf) S4? Both are working fine. (The issue with tty1/tty7 and logout/login is still there). My last test involved the live DVD from Ubuntu 15.10 x86_64 (Kernel 4.2.0-16-generic #19). And this is bad news for my dear old SuSE of 18 years friendship: Ubuntu worked out of the box: S3/S4, switching the console to tty1 and back to tty7, sound was there and even the USB front panel (that does not work with Leap 42.1) is OK and responding correctly ... Shall I do a heart/kernel transplant? Would it work (just copy the Ubuntu kernel tree to the proper places)? Would there be a safe way back? I guess, I could grab the vanilla kernel sources and build it myself. Is there a kernel 4.2 for openSUSE in the pipeline? -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=959245 http://bugzilla.opensuse.org/show_bug.cgi?id=959245#c25 --- Comment #25 from Takashi Iwai --- Oh, only for making the laptop panel working, there are several easy workarounds. (A) Pass nomodeset boot option. Passing nomodeset boot option makes the system skipping native graphics driver, and instead using EFI framebuffer. This is the reason why openSUSE 13.2 and Ubuntu worked. Prior to 4.2 kernel, i915 driver's support for Skylake is incomplete, and 4.1.x on Leap has still known bugs as you experienced although the Skylake support was enabled as default. Of course, with EFI fb, there can be no mode change and no proper support of external output hotplug, and has 3D only in soft-rendering by CPU. But eDP modeset should work as is, at least. In this bug report, I've tried to improve i915 KMS on 4.1.x kernel, but it's not so trivial because of radical code changes in each kernel. So slowly getting fixed, but, as you see, there are a few issues left yet. (B) Use 4.2 or newer kernels. We provide always the latest stable kernel and development kernel in OBS repository, as opt-in. You can get the 4.3.x kernel from OBS Kernel:stable repo, http://download.opensuse.org/repositories/Kernel:/stable/standard and 4.4-rc kernel from OBS Kernel:HEAD repo, http://download.opensuse.org/repositories/Kernel:/HEAD/standard Either download kernel-default.rpm manually and install it via "zypper in", or register the URL above and let zypper fetch it. GRUB2 supports multi-version kernel boot, so it's fairly safe to try it out. However, as already mentioned, there seem a few other bugs in 4.3.x or 4.4-rc kernels. Some of them have been already addressed, but some other might still hit. At least, the bug you reported here has been already fixed in these kernels, though. I have also kernel packages of other versions in my own OBS repo. For example, for 4.2.x, you can find in OBS home:tiwai:kernel:4.2 repo, http://download.opensuse.org/repositories/home:/tiwai:/kernel:/4.2/standard/ This is provided unofficially and unsupported, so use at your own risk. -- You are receiving this mail because: You are on the CC list for the bug.
