Integrated and Discrete graphics on the P1G2

2020-11-06, 11:49 AM

I recently fully reinstalled my linux system. I installed Fedora 33 and downloaded the Nvidia driver using this page. To see which graphics cards are being used I did this:

➜  ~ lspci -vnnnn | grep VGA

00:02.0 VGA compatible controller [0300]: Intel Corporation UHD Graphics 630 (Mobile) [8086:3e9b] (prog-if 00 [VGA controller])

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation TU117GLM [Quadro T1000 Mobile] [10de:1fb9] (rev a1) (prog-if 00 [VGA controller])

 

I think the [VGA controller] at the end means that the graphics card is being used so they are both used. However, I get less performance then previously on F32 when I set in the BIOS 'discrete graphics mode'. Will the driver I have not automatically switch between integrated and discrete graphics? When I click right mouse button on an application it shows 'launch using discrete graphics card' but this did not improve any performance. My driver version is 455.38:

➜  ~ dnf list installed | grep nvidia

akmod-nvidia.x86_64                                3:455.38-1.fc33                        @rpmfusion-nonfree-nvidia-driver

kmod-nvidia-5.8.17-300.fc33.x86_64.x86_64          3:455.38-1.fc33                        @@commandline                  

nvidia-settings.x86_64                             3:455.38-1.fc33                        @rpmfusion-nonfree-nvidia-driver

xorg-x11-drv-nvidia.x86_64                         3:455.38-1.fc33                        @rpmfusion-nonfree-nvidia-driver

xorg-x11-drv-nvidia-kmodsrc.x86_64                 3:455.38-1.fc33                        @rpmfusion-nonfree-nvidia-driver

xorg-x11-drv-nvidia-libs.i686                      3:455.38-1.fc33                        @rpmfusion-nonfree-nvidia-driver

xorg-x11-drv-nvidia-libs.x86_64                    3:455.38-1.fc33                        @rpmfusion-nonfree-nvidia-driver

I also have a different NVIDIA X Server Settings application now, it has less options. It used to show things about my screen and other things. It now looks like this:

Is something wrong with my driver? When I launch nvidia-settings from the terminal it still gives exactly this windows but also this error message:

(nvidia-settings:35337): GLib-GObject-CRITICAL **: 12:47:43.531: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

 

Does Lenovo not support both graphics cards for Fedora?

Hello,

 

Has upgrading your fedora 33 installation resolved this problem?

 

Which graphical desktop environment are you using?   The latest Gnome versions by default do NOT use X libraries.  It looks like the nvidia drivers you installed use the X libraries.  I use KDE Plasma desktop environment which has not converted away from X yet, but they are proudly working on converting away from X :(    It is possible to start Gnome in Xorg mode, Have you tried that?

 

Sincerely,

Usedtoberich
