Another thing to try: Change to "on-demand" mode. (I'm not sure, but this may require another reboot or log out): sudo prime-select on-demand
Verification (first command should show AMD and second command Nvidia): glxinfo -B __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxinfo -B If all goes well, you can run programs on the Nvidia GPU by by setting the variables as in the previous command. Or, if you don't want to type all that every time, you can make a new command. Note that this long command is all one line: alias prime_run=__NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia To make the alias permanent, add the line to the end of ~/.bashrc file -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1894852 Title: Graphics slow on hybrid AMD/Nvidia laptop Status in xorg package in Ubuntu: Incomplete Bug description: I selected the nvidia driver as I did not know which package to select. I am pretty sure that is not the problem as that driver is supposed to support the hybrid graphics in this laptop. What I was expecting on the clean install of Kubuntu was to use the dedicated Nvidia video card for graphics and I do believe with these hybrid graphics is it supposed to use the on CPU graphics for less intensive graphics. Personally, I would be happy if the dedicated Nvidia card was only used at this point. What has happened is the system is showing AMD RENOIR (DRM 3.38.0, 5.8.0-18-generic, LLVM 10.0.1) in the info centre and the VMWare driver is also showing in Steam. The games I have tried to launch in steam are running at about 1FPS and I have tried games like Farming Similator 2013 which are very old and this computer should be able to run at well above 60FPPS. I get the same problem on Kubuntu 20.04.01 as well as 20.10. Running the Nvidia X Server Settings shows the proper video driver and video card, but it does say None beside display devices. I tried hours to try and fix this problem. I first thought it was a driver issue, but tried deveral different version of the proprietary Nvidia driver with no change. I made sure I am using the latest driver only released a couple months ago still with no change. The open source driver only shows a blank screen. I then thought maybe the computer is only using the on CPU Ryzen graphics; even though that should still get better than 1 FPS. So, I tried solutions to force the dedicated video card. sudo prime-select nvidia says the nvidia profile is already set. The nvidia settings does not have any setting to force the video card as well. prime- select query shows nvidia as well. Most solutions seem to be for intel chipsets with the Nvidia 1050 and I have an AMD with Nvidia 1050.
