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:
