Connect 2 monitors to Dell Laptop G3 15 on Fedora 32

-
If you are trying to connect 2 monitors (HDMI + USB C), you might find that only USB C and the laptop monitors is working in Fedora 32. After I search around, here is the simple solution.

Create a file (any file name end with extension .conf) under folder /etc/X11/xorg.conf.d.

I name it 11-nvidia-prime.conf. (Copy from ubuntu). Enter the lines below and reboot. 

[root@localhost xorg.conf.d]# cat 11-nvidia-prime.conf
Section "OutputClass"
    Identifier "Nvidia Prime"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    Option "IgnoreDisplayDevices" "CRT"
    Option "PrimaryGPU" "Yes"
EndSection

I believe this solution should be working for Fedora 25 and above.

Leave me a message if you have question.

Fedora 19 with kernel 3.10 fail to install vmplayer module.

If you are having problem start up vmware player on Fedora 19 after upgrade kernel to 3.10, here is the solution. Basically it is due to the procfs interface and vmnet not able to compiles. First download the procfs patch from http://communities.vmware.com/thread/446113?start=0&tstart=0 .If you don't have time to read the forum, here is the link of the procfs patch. Or you can use the following command: # tar xf /usr/lib/vmware/modules/source/vmnet.tar # cd vmnet-only # wget  http://communities.vmware.com/servlet/JiveServlet/download/2239207-108590/procfs.patch # patch -p1 < procfs.patch # cd .. # tar -cvf vmnet.tar vmnet-only/ # cp vmnet.tar /usr/lib/vmware/modules/source/ This will patch the procfs interface. Secondly download the vmnet patch from http://mysticalzero.blogspot.com/2013/07/vmblock-patch-for-linux-310-vmware.html . The link of the patch is here . Or you can use the following command: # tar xf /usr/lib/vmware/modules/source/vmblock.tar

What are filesystem capabilities?    For the purpose of performing permission checks, traditional Unix implementations distinguish two categories of processes: privileged processes (whose effective user ID is 0, referred to as superuser or root), and unprivileged processes (whose effective UID is non-zero). Privileged processes bypass all kernel permission checks, while unprivileged processes are subject to full permission checking based on the process's credentials (usually: effective UID, effective GID, and supplementary group list).  Starting with kernel 2.2, Linux divides the privileges traditionally associated with super
