Selinux is the culprit here. You need to turn it off. Best way to do it is sudo setenforce 0 You may enable is again using sudo setenforce 1

It does remember the setting but the setting makes the brightness go max whenever the power is plugged in. I want to be able to give it a custom value when the power is plugged in so that it doesn't default to max. Is there any such setting that listens to power plug event in gnome or fedora ? That setting will fix this issue.

This works :D But only via terminal Coulfn't this be made persistent so monodevelop could be launhed from launcher than the terminal ?

I suggest to first check if your NVIDIA has optimus technology and if so use the Bumblebee project. Check my answer here on a similar question:

First you need to verify if your grapphics card has Nvidia Optimus (either you can see for NVIDIA Optimus logo on your laptop or you can check this from your laptop manufacturer specification page) or is it impossible to turn off (which is not even needed) the Intel driver / NVIDIA Optimus from BIOS . To check this use

lspci |grep -i VGA

You are a candidate of this resolution if you get something like (I'm too an Optimus "Prime" holder :P )

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [GeForce 610M] (rev ff)

Just follow the Bumblebee Project for your Fedora version and you should be good to go. It will use the stock NVIDIA driver blob. I suggest to install both the Bumblebee (with nouvea drivers) and Bumblebee with NVIDIA proprietary drivers. This way the shared optimus technology will work best. Installing Primus also won't do any harm. After you reboot, the OS will use NVIDIA whenever needed as per the Optimus technology.

yeah. got it. Silly mistake. Installed it on my windows guest by mounting the image. Can share folders now. Thanks :)

2013-07-26 03:50:36 -0500 asked a question Unable to install VirtualBox-guest

I installed VirtualBox from the terminal using

sudo yum install VirtualBox

But need VirtualBox guest Additions for shared folder access of the host system. Tried installing from terminal using

sudo yum install VirtualBox-guest

enountered the following dependency error

Loaded plugins: langpacks, refresh-packagekit

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

It comes out that either i could install VirtualBox or VirtualBox-guest however i need both. Even after i tried installing VirtualBox guest additions using the image downloaded using VirtualBox menu command, still got some modprobe error

(modprobe vboxguest failed)

None of the method seem to work. Are there some kernel issues here ?
