Had this issue occasionally last year on Ubuntu 20.04, but now every single time in the past week after my laptop wakes up from sleep.
Laptop is an Asus TUF F15 gaming laptop, with an NVIDIA 2060 GPU (hybrid graphics with Radeon Renoir GPU). CPU is an AMD Ryzen 7 4800H. NVIDIA driver 460.91.03. Ubuntu 20.04.3 LTS with Xfce 4.14. Kernel version 5.6.14-050614-generic, dual monitors, one connected to the HDMI port from the USB-C adaptor (DP-0, connected directly to the NVIDIA GPU), and the other one connected to the HDMI port on the laptop (HDMI-1-1, graphics "pass-through" AMD Radeon GPU). see https://forums.developer.nvidia.com/t/ubuntu-19-04-doesnt-detect-my- hdmi-display/79577/80 When waking up, the DP-0 port (via USB-C, driven by NVIDIA GPU) does not have this issue, but the HDMI-1-1 port (via AMD GPU pass-through) loses cursor. The workaround Ctrl+Alt+F1 followed by Alt+F7, as provided in #1573454 works. Looking for a permanent fix. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1568604 Title: Mouse cursor lost when unlocking with Intel graphics Status in elementary OS: Fix Released Status in xf86-video-intel: Confirmed Status in xserver-xorg-video-intel package in Ubuntu: Fix Released Status in xserver-xorg-video-intel source package in Trusty: Won't Fix Status in xserver-xorg-video-intel-lts-xenial source package in Trusty: Won't Fix Status in xserver-xorg-video-intel source package in Xenial: Fix Released Status in xserver-xorg-video-intel package in Debian: Fix Released Bug description: [Relevant details] This bug also affects Trusty and all distributions based on it, like Elementary OS Freya. [Impact] Mouse cursor is no longer visible after VT-switch for systems with Intel graphics. Switching VTs again may cause the cursor to become visible again. - Changing to vt1 then back to vt7 (ctrl+alt+f1 then ctrl+alt+f7) This is often observed in systems that lock the session and return to the greeter (including at least Xubuntu, Ubuntu Mate, and elementary OS). [Test Case] (Requires a lightdm-based screen locking solution) 1. Start a new session. 2. Lock your screen. 2a. You are redirected to the lightdm greeter. 3. Login/Unlock your session. 4. Cursor is no longer visible. [Regression Potential] remains to be seen === [Original Report] Cursor is visible at unlock screen either after returning from suspend or just locking. After unlocking screen cursor is invisible. Changing to vt1 then back to vt7 (ctrl+alt+f1 then ctrl+alt+f7) cursor returns ==================== no matter if you suspend or sleep, to swap or disk when you return from it, the mouse cursor is missing. you can still move the mouse and you can see (because it highlights the window) as you move it around. But the cursor is not displayed on the screen. i am using a lenovo W540 laptop. I downloaded the latest beta on april 8 2016. this is xubuntu using the xfce window manager. the cursor does return if i log off and log back in, but that actually defeats the purpose of going to sleep. --- ApportVersion: 2.20.1-0ubuntu1 Architecture: amd64 DistroRelease: Ubuntu 16.04 InstallationDate: Installed on 2016-04-08 (2 days ago) InstallationMedia: Xubuntu 16.04 LTS "Xenial Xerus" - Beta amd64 (20160323) NonfreeKernelModules: nvidia_uvm nvidia_modeset nvidia Package: light-locker 1.7.0-2ubuntu1 PackageArchitecture: amd64 ProcEnviron: LANGUAGE=en_US TERM=xterm PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 4.4.0-18.34-generic 4.4.6 Tags: xenial Uname: Linux 4.4.0-18-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/elementaryos/+bug/1568604/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
