** Description changed:
On 2019-04-03 I updated to the latest linux-image-generic-
hwe-18.04:amd64 and then I got on a trip where things worked fine at
first. Back home I realized that the new version 4.18.0-17-generic has
issues initializing gnome with multiple monitors.
Steps to reproduce:
- boot into 4.18.0-17-generic
- start Ubuntu Desktop (gdm works fine at first)
- Log in
I have found that this only triggers:
- with multiple monitors attached ( I have laptop fullHD + 2* external fullHD)
- only with 4.18.0-17-generic, 4.18.0-16-generic seems fine
(=>upgrade-regression?)
On init of the gnome shell the system crashes with:
kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A
FIFO underrun
[drm:pipe_config_err [i915]] *ERROR* mismatch in pixel_rate (expected 148500,
found 296999)
[drm:pipe_config_err [i915]] *ERROR* mismatch in shared_dpll (expected
00000000d293602a, found 000000007548bc60)
[drm:pipe_config_err [i915]] *ERROR* mismatch in dpll_hw_state.ctrl1
(expected 0x00000003, found 0x00000001)
[drm:pipe_config_err [i915]] *ERROR* mismatch in
base.adjusted_mode.crtc_clock (expected 148500, found 296999)
[drm:pipe_config_err [i915]] *ERROR* mismatch in port_clock (expected 270000,
found 540000)
+ Only resolves with a hard shutdown (5 sec power press), pressing it
+ shortly doesn't help - also the keyboard shortcuts for and further e.g.
+ CTRL+ALT+F* does not switch to consoles anymore.
I'll attach a full journal of the system and run an apport run on it.
Let me know if I can help any further.
