Hello. I have been using Mageia 7.1 for about the last month, and I think I may have found a bug that occurs whenever I install the proprietary nvidia-current driver for my PC's GeForce 750Ti GPU. I'm currently running KDE Plasma 5, but I also encountered this issue using XFCE. I used Mageia Control Center to configure and install the driver. The driver installs fine. However, certain applications that use OpenGL fail to launch when using the proprietary Nvidia driver, giving a LibGL.so error in the terminal. These applications do work as normal when the nouveau driver is used. Below is the output from projectM-pulseaudio after switching to the nvidia-current driver: ------------------------------- [--REDACTED--@localhost ~]$ projectM-pulseaudio dir:/usr/share/projectM/config.inp reading ~/.projectM/config.inp kf5.kio.core: "Could not enter folder tags:/." libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast Similar errors occur with qv4l2, which I use to configure my Dazzle DVC100 analog video capture device. I can fix the error by using a solution I found on the Ubuntu forums that outline an almost identical issue. https://askubuntu.com/questions/834254/steam-libgl-error-no-matching-fbconfigs-or-visuals-found-libgl-error-failed-t/1154964 It appears my OpenGL applications I use on my Mageia installation are still trying to use the old libGL.so when they are supposed to use nvidia's libGL.so. Here is the terminal output from running the "ldconfig" command outlined in the forum posting: ------------------- [root@localhost --REDACTED--]# ldconfig -p | grep -i gl.so libwayland-egl.so.1 (libc6,x86-64) => /lib64/libwayland-egl.so.1 libQt5OpenGL.so.5 (libc6,x86-64) => /lib64/libQt5OpenGL.so.5 libOpenGL.so.0 (libc6,x86-64) => /usr/lib64/nvidia-current/libOpenGL.so.0 libOpenGL.so.0 (libc6) => /usr/lib/nvidia-current/libOpenGL.so.0 libGL.so.1 (libc6,x86-64) => /usr/lib64/nvidia-current/libGL.so.1 libGL.so.1 (libc6,x86-64) => /lib64/libGL.so.1 libGL.so.1 (libc6) => /usr/lib/nvidia-current/libGL.so.1 libEGL.so.1 (libc6,x86-64) => /usr/lib64/nvidia-current/libEGL.so.1 libEGL.so.1 (libc6,x86-64) => /lib64/libEGL.so.1 libEGL.so.1 (libc6) => /usr/lib/nvidia-current/libEGL.so.1 If I delete the libgGL.so.1 symlink in the /lib64 folder, qv4l2 starts working again. I also experience no other issues running other OpenGL applications or games, and Mageia runs smooth and stable. I don't know if this is a specific bug with my computer, or an issue with the particular nvidia-current packages.
Thank you Wade for your detailed & helpful report. This looks similar to bug 25204 (NVIDIA GP102 [GeForce GTX 1080 Ti]), but I cannot say they are effectively duplicates - the same problem. If they are, please mark this bug as a duplicate of the older one. Assigning similarly to the kernel/drivers people.
