[opensuse-factory] Flickering screen (and worse)
I've been having trouble with an intermittently flickering screen on my laptop for the past few weeks. About half the time, it's minor, just flickering for a few seconds, but it can get worse, lasting for a minute or two and blanking large (nearly all) of the screen. The worst incidents will end with the following in the log: Jul 24 15:44:50 homelap7 kernel: i915 0000:00:02.0: [drm] HPD interrupt storm detected on connector eDP-1: switching from hotplug detection to polling After this, the flickering stops. Searching, I noticed issues like this associated with the i915 driver over the past few years, so I though I'd ask if there might be a cause in recent Tumbleweed releases. Otherwise, I guess I'm off to the local computer repair shop. Here's some hopefully-relevant information about the graphics card:

There is a lot of discussion about this over the past two years. The freedesktop bug was: [drm] HPD interrupt storm detected on connector HDMI-A-1 : switching from hot... https://bugs.freedesktop.org/show_bug.cgi?id=106675 This was supposed resolved in the 4.18 kernel release. However, a search with "interrupt storm switching from hotplug to polling" discloses pages of questions for just about every distribution. A regression is a possibility, other than that, I am no where near familiar enough with hardware to know what would trigger the message, or even if flaky hardware is capable of triggering the problem. -- David C.

Now that you mention it, I have observed some flickering in my laptop after coming back from suspend to ram. I thought it was hardware related, but after reading your post I will observe the log the next time it happens. But on Leap 15.1 -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

This is just a guess, but have you tried adding "i915.enable_psr=0" to the kernel parameters at boot (hit 'e' when the bootloader shows up, add the above snippet right after '...splash=silent quiet' on the same line)? There have been issues with the i915 graphics flickering that have been helped with this, perhaps at the cost of somewhat higher power usage [see e.g. < https://wiki.archlinux.org/index.php/Dell_XPS_13_(7390)>].

Cheers, This seems the easiest suggestion, so I've started with it. The flickering doesn't happen every day, so it may take a while before I know if it works.

Thanks. Note, though, that the log entry doesn't always appear, only when the flickering is severe (/e.g./, lasting a minute or more, or blacking-out large portions of the screen. On 7/25/20 9:30 PM, Felix Miata wrote:

I thought the same thing. It seems to be the only one with a "-32bit" version, though. Strange.
I got some flickering with "i915.enable_psr=0", so I've removed it and have installed xf86-video-intel and xf86-video-intel-32bit, which pulled in libvdpau_va_gl1, libvulkan_intel, libxcb-util1-32bit, libXv1-32bit, libXvMC1, and libXvMC1-32bit. I haven't seen any flickering since installing these, but it has been very long. Also...

I am still having flickering woes, and I'm increasingly convinced that simply installing xf86-video-intel and xf86-video-intel-32bit isn't sufficient to actually switch to the intel DDX, instead of modesetting. (See below.) Can anyone shed some light on how to switch from modesetting to intel? I have the feeling that the wiki's documentation may be out of date (or things aren't working as they should).

For me it does work that way, at least for the normal Xorg. There, intel has higher priority than modesetting, and just by having xf86-video-intel installed it uses it (32bit isn't needed in my case). /var/log/Xorg.0.log confirms that intel is used (see excerpt below). This is with a HD530 (Skylake) GPU. But you seem to use Wayland?

You did run inxi to generate this after a full X restart, right? If so, then there may be a configuration file specifying use of the modesetting driver, or /etc/X11/xorg_pci_ids/modesetting_ids is more than 2 bytes and specifying an override. Does /etc/X11/xorg.conf.d/50-device.conf exist and contain uncommented lines, including one that specifies modesetting as device? If not, is there some other file specifying modesetting?

Thanks, Felix! Yours and Peter's comments gave me a new path for investigation. I logged into Gnome using X11, rather than Wayland, and now I'm using the intel driver: > inxi -Gxx Graphics: Device-1: Intel UHD Graphics 620 vendor: CLEVO/KAPOK driver: i915 v: kernel bus ID: 00:02.0 chip ID: 8086:3ea0 Device-2: Chicony Chicony USB2.0 Camera type: USB driver: uvcvideo bus ID: 1-7:3 chip ID: 04f2:b649 Display: x11 server: X.Org 1.20.8 compositor: gnome-shell driver: intel unloaded: fbdev,modesetting,vesa resolution: 1920x1080~60Hz s-dpi: 96 OpenGL: renderer: Mesa DRI Intel UHD Graphics 620 (WHL GT2) v: 4.6 Mesa 20.1.4 compat-v: 3.0 direct render: Yes So it seems that Wayland doesn't use the intel DDX if it's installed, but X11 does. I'll run like this for a while to see how it goes. If it goes OK, I'll switch back to the modesetting DDX but stay with X11 to see if its the DDX or Wayland. Specific comments below.

None of these three files exist on my system. I have to admit it'd be nice to know where Xorg.0.log is; I'm running the 20200729 Tumbleweed snapshot and have always been staying pretty current.

In some environments, maybe only some distros, it's ~/.local/share/xorg/Xorg.0.log which is sometimes copied to /var/log/Xorg.0.log. Historically, and in every openSUSE environment I've used, it's always been /var/log/Xorg.0.log. Note too that in some situations X will run in an additional session, such as using startx from a vtty while a display manager is running. In those situations the 0 will be replaced by a 1, or if a third session, a 2. Previous sessions' logs are saved by the same name except with .old appended. With Wayland sessions, I have no idea if there automatically exists any such log as a discrete file, but IIRC, in Fedora at least, equivalent information shows up in the journal if the session is Gnome, and maybe for other DEs/WMs too. -- Evolution as taught in public schools is religion, not science.

Thanks, Felix and Patrick. The Xorg logs are in ~/.local/share/xorg, not /var/log (or its subdirectories). It is also available in the journal with a type of "/usr/lib/gdm/gdm-x-session" when using X11. When using Wayland, it's is not in the journal. And things get more confusing... I switched back to Wayland from X11 to generate a Xorg.0.log to help debug why the intel DDX was not selected, and Wayland came up with the intel DDX selected: > inxi -Gxx Graphics: Device-1: Intel UHD Graphics 620 vendor: CLEVO/KAPOK driver: i915 v: kernel bus ID: 00:02.0 chip ID: 8086:3ea0 Device-2: Chicony Chicony USB2.0 Camera type: USB driver: uvcvideo bus ID: 1-7:3 chip ID: 04f2:b649 Display: wayland server: X.Org 1.20.8 compositor: gnome-shell driver: intel unloaded: fbdev,modesetting,vesa resolution: 1920x1080~60Hz s-dpi: 96 OpenGL: renderer: Mesa DRI Intel UHD Graphics 620 (WHL GT2) v: 4.6 Mesa 20.1.4 compat-v: 3.0 direct render: Yes (In case it's not clear, I "switch" between X11 and Wayland by selecting one or the other in GDM when I log in.) My guess is that the log is no longer of use, since it shows a successful selection of intel, but the Xorg.0.log is in https://paste.opensuse.org/60046995, if it does have value. Since i'm now up on Wayland with the intel DDX, I'll stay there to see what happens. I'll then try X11 with the intel DDX if that seems warranted. Is this occupying too much bandwidth on the list? I can move this to bugzilla, if so. It's probably two or three issues: 1) the screen flickering, 2) non-selection of the intel DDX, and maybe 3) documentation of where the logs are kept. Let me know your preference. Thanks for all the time you're spending on this. David On 7/31/20 2:06 PM, Felix Miata wrote:

Hi David, There is a dedicated mailing list "opensuse-support" for support topics like this specifically. Let's draw a line under this thread; this ML is dedicated to topics related to openSUSE development.
