Hi, Since long time I regularly noticed a problem with nvidia-drivers, usually at each driver update. The old driver is currently loaded : > # lsmod > Module Size Used by > btusb 49152 0 > btrtl 16384 1 btusb > nvidia 16748544 1 > i2c_i801 24576 0 > btbcm 16384 1 btusb > btintel 16384 1 btusb > nct6775 53248 0 > hwmon_vid 16384 1 nct6775 > coretemp 16384 0 After a world update, a new version of the drivers was installed. I just want to unload the old module, and load the new one, but it does not work. > # modprobe -v -r nvidia > remove modprobe -r --ignore-remove nvidia-drm nvidia-modeset nvidia-uvm nvidia > modprobe: FATAL: Module nvidia-uvm not found. > modprobe: FATAL: Error running remove command for nvidia nvidia-drivers package is emerged with uvm useflag disabled, which is the default configuration. Then, the only way to get Xorg running is to reboot. I found similar bug #578126 which was never fixed. Thanks.
