[Kernel-packages] [Bug 2060268] Re: Phantom "Unknown Display" shown in Settings after installing the Nvidia driver
Another Workaround: This is using the Nvidia driver and not nouveau, right? I believe this is a driver in the Nvidia driver that is not asking for the conflicting framebuffers to be unregistered. You can try to add "initcall_blacklist=simpledrm_platform_driver_init" to your kernel command line parameters to prevent the simpledrm driver to not be loaded. Add to your kernel command line this. Open your terminal: sudo nano /etc/default/grub add "initcall_blacklist=simpledrm_platform_driver_init" to where it says GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash..., so it looks like this: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash initcall_blacklist=simpledrm_platform_driver_init” ctrl+O for save and ctrl+X for quit. Back in the terminal write: sudo update-grub rebbot This fixed the issue for me. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-470 in Ubuntu. https://bugs.launchpad.net/bugs/2060268 Title: Phantom "Unknown Display" shown in Settings after installing the Nvidia driver Status in linux package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-470 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-535 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-545 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-550 package in Ubuntu: Confirmed Bug description: [ Impact ] After installing Nvidia driver 545 on a single (27") monitor system, Settings shows a phantom 46" monitor of the same resolution.
