[Desktop-packages] [Bug 1604742] Re: Black screen when booting without nomodeset
Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. Ubuntu 16.04 (xenial) reached end-of-standard-support on April 29, 2021. I'm setting the status of this bug to 'Incomplete' as it's not seen any activity for some time. If this is still an issue when using a currently maintained release of Ubuntu then please let us know which one(s) otherwise this bug report can be left to expire in approximately 60 days time. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1604742 Title: Black screen when booting without nomodeset Status in Ubuntu: Incomplete Bug description: It happens intermittently. Some times after a kernel upgrade it boots fine, but immediately after the screensaver turns on the screen gets black with the backlight on. After a good boot it returns to booting to a black screen. The system is working while the black screen is on. I am able to log in and shutdown via console (blindly) I have tried to write dmesg to a file while it is in this mode and I got this: [ 1835.947242] cfg80211: (5815000 KHz - 585 KHz @ 35000 KHz), (N/A, 3301 mBm), (0 s) [ 1835.947243] cfg80211: (1710 KHz - 1730 KHz @ 20 KHz), (N/A, 2000 mBm), (N/A) [ 1835.947244] cfg80211: (5700 KHz - 6600 KHz @ 216 KHz), (N/A, 4000 mBm), (N/A) [ 1835.952825] wlp3s0: Limiting TX power to 18 dBm as advertised by 04:da:d2:fd:7d:0e [ 1998.759411] [drm:intel_dp_link_training_clock_recovery [i915_bpo]] *ERROR* too many full retries, give up [ 1998.770230] [drm:intel_dp_link_training_clock_recovery [i915_bpo]] *ERROR* too many full retries, give up [ 1998.781095] [drm:intel_dp_link_training_clock_recovery [i915_bpo]] *ERROR* too many full retries, give up [ 1998.791896] [drm:intel_dp_link_training_clock_recovery [i915_bpo]] *ERROR* too many full retries, give up [ 1998.802880] [drm:intel_dp_link_training_clock_recovery [i915_bpo]] *ERROR* too many full retries, give up [ 1998.813780] [drm:intel_dp_link_training_clock_recovery [i915_bpo]] *ERROR* too many full retries, give up [ 1998.824569] [drm:intel_dp_link_training_clock_recovery [i915_bpo]] *ERROR* too many full retries, give up [ 1998.824747] [drm:intel_dp_start_link_train [i915_bpo]] *ERROR* failed to train DP, aborting This was after a boot failed.
