I am using Fedora 22 and having problems with my Nvidia GeForce GTX765M driver. I cannot adjust my laptop screen brightness and cannot output video from hdmi. I did a little research here and on fedora forums and here are some points that might be useful to diagnose the problem:
Nouveau driver is installed already
sudo dnf install *nouveau*gives the result:
Package xorg-x11-drv-nouveau-1:1.0.11-2.fc22.x86_64 is already installed, skipping. Dependencies resolved. Nothing to do. Complete!xorg.conf has no entry related to backlight or nvidia:
ls /etc/X11/xorg.conf.dgives the result:
00-keyboard.conf 50-synaptics.confwhich are obviously related to keyboard and touchpad.
/sys/class/backlight directory is empty.
lspci related results are:
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06) ... 01:00.0 3D controller: NVIDIA Corporation GK106M [GeForce GTX 765M] (rev a1)Nvidia driver is suppressed (although i did try commenting that line and rebooting too, didn't work):
cat /usr/lib/modprobe.d/dist-blacklist.confgives:
... # framebuffer drivers blacklist aty128fb blacklist atyfb blacklist radeonfb blacklist i810fb blacklist cirrusfb blacklist intelfb blacklist kyrofb blacklist i2c-matroxfb blacklist hgafb blacklist nvidiafb #HERE IT IS! blacklist rivafb blacklist savagefb blacklist sstfb blacklist neofb blacklist tridentfb blacklist tdfxfb blacklist virgefb blacklist vga16fb blacklist viafb ...
Any other suggestions? I merged my two questions (backlight and hdmi) assuming both were stemming from same problem, but i may be mistaken in that. Thanks in advance.
