Public bug reported: Hello,
after upgrading to 20.10 from 20.04LTS I have the following issue: I have a laptop in docker with 3 external screens connected (1 VGA, 2 HDMIs). If I close the laptop lid all external screens work but when I start citrix workspace my screens start to flicker then xorg restarts and citrix either starts on an external screen or on the closed laptop screen. This was working without errors on 20.04 release. Could you pls check? Thanks, Zoltan ProblemType: Bug DistroRelease: Ubuntu 20.10 Package: xorg 1:7.7+19ubuntu15 ProcVersionSignature: Ubuntu 5.8.0-25.26-generic 5.8.14 Uname: Linux 5.8.0-25-generic x86_64 .tmp.unity_support_test.0: ApportVersion: 2.20.11-0ubuntu50 Architecture: amd64 BootLog: CasperMD5CheckResult: skip CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Fri Oct 23 18:34:19 2020 DistUpgraded: Fresh install DistroCodename: groovy DistroVariant: ubuntu GraphicsCard: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) Subsystem: Dell 4th Gen Core Processor Integrated Graphics Controller [1028:05bd] InstallationDate: Installed on 2014-11-24 (2160 days ago) InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Release amd64 (20141022.1) MachineType: Dell Inc.
