I am a new commer to linux... I have just a few week of experience with Linux under Ubuntu 13, but had to change last minute to RHEL because got frustrated with compatibility issues with CUDA and NVidia Driver and Mathematica installations .

But I am frustrated because I can not get anything isntalled in the graphical interface. I followed the Install ./ command and installation proceeded as successfull. But I dont get anything in the graphical interface.

The same thing happened when installing Dropbox in RHEL.

I have gone online... But I can not find a straight total begginers guide for RHEL. Please, need a direction. Anyone here have an idea what is I am going wrong?

do you mean you don't get the entry in menu to start application? you can still create launcher on desktop anyway.

It sounds like it's installed. This isn't Windows, installed programs rarely put "shortcuts" in your "start menu". Open a terminal, and run the program you installed, often you just type its name.

If you must have a launcher somewhere on your desktop, then make one, once you use the command line to figure out how it needs to be called.

If you're a newcomer to Linux, RHEL is NOT a good choice. It is designed for SERVERS...so hardware like nVidia cards, bluetooth, sound, etc., can be problematic to get working, if they work at ALL. More importantly, RHEL needs to be PAID FOR...without a subscription, you will NOT get access to online repositories, bugfixes, security updates, and will NOT be able to install packages easily. You're setting yourself up for LOTS of difficulties down the road.

For a new user, consider either Fedora (soon to be release 20), which will keep you with the RPM/yum package system, or Mint. Both are MUCH easier to load, and have broader 'consumer-grade' hardware support than RHEL. The nVidia driver is simple to install, if you download it from the nVidia site, and if you install the kernel source when you build your system, you can get a custom-built driver just by running the installation program.

Mathematica can be downloaded from:
https://www.wolfram.com/mathematica/...uirements.html

...where Fedora is listed as a supported option. Support only goes to 17, but I'd be surprised if 19 doesn't work...same goes for Mint with the Debian instructions. That is only a free, 30 day trial...so if you're paying for Mathematica, you should be able to contact Wolfram support for assistance.

Centos 6 is a reasonable choice for either a Desktop or Server and is not all that difficult for a newcomer (I am only a moderate user) There is a guide to installing Dropbox available also.

Noted, but just starting out, centos or othr red hat based distros would not be that easy to get up and running quickly. For the problems you are facing. Try whereis command or yum search to confirm instalation. If installed check selinux and booleans. That might not play so nice with the programme.

Note, try not using typical advice to turn off selinux. Check your audit log for mvc type entries.

Note also on centos 6.4 if you use selinux and want services confined, do not manually restart services as this causes the service to run in an unconfined domain. Better to test and then reboot the machine.

as per above
RHEL 6.4 is also not a free OS
so i take it you ALREADY DID BUY the required support contract
you know the one that is $299 per year for the standard 1 year contract

if not then do NOT use RHEL , instead install CentOS 6.4

but as per above RHEL/CentOS/ScientificLinux are NOT a good choice for "new to Linux users"
installing the CUDA 5.5 SDK however is rather easy
SEE: https://developer.nvidia.com/cuda-downloads
and use the rpm or the .run

installing the nvidia.run driver and replacing the ALREADY installed "nouveau" driver.
is going to require
1) uninstalling nouveau
2) black listing nouveau
3) rebuilding the boot image WITHOUT Nouveau!!!
4) install the .run driver from booting into TEXT ONLY MODE !!!!! runlevel 3

This is a lot of work

as to " Mathematica installations ."
install that on windows 7

there is a FREE GPL'ed clone called "Octave"
that is in the CentOS repos and likely in the redhat RHN repo you have access to with the REQUIRED support contract
the QT front end is nice
and you will NOT find one
it dose not exist
the redhat documentation ( seeing as rhel is made for SERVERS ,primarily !!! ) assumes that YOU are already a computer system administrator with years of experience
but here it is
https://access.redhat.com/site/docum...erprise_Linux/
PS. CentOS and ScientificLinux also use this EXACT same documentation
they point people to the red hat docs .


red hat is NOT for someone that wants a "point and click" replacement for windows
IT IS NOT a windows replacement!!!

All true

Not really, in fact it's pretty straight forward. Just a few simple commands actually, trivial if you have a guide to follow.

Octave is a clone of Matlab, not Mathmatica. Big difference.

Hi, http://www.linuxquestions.org/questi...-in-all-35750/

matlab and mathmactica

i do that all the time , and to think i use Octave a fair amount of time

true installing the nvidia.run on RHEL really is not that hard
- some of us have been using that driver for 8 years

but for a new to linux user
rebuilding the boot image with "dracut" is a rather daunting challenge
then having to ignore EVERY older guide about setting int5 to int3
then stopping the boot to add a 3 to the end of the boot line and continue with the boot

that is a bit hard

but there is also the kmod-nvidia , but i am not sure that is in RHN

That's true, it can be a bit of a pain to find the right guide for your OS that includes all of the necessary steps. Often you have to piece together a step or two from multiple guides, which would be daunting for a beginner.

Unless you have a RHEL license, you would better use Scientific Linux
which is a free clone of RHEL developped by CERN and Fermilab. If you need a replacement for Mathematica, you can consider Reduce (you will have to build it from source) or Maxima (there are RPM packages for Maxima, but Reduce is more powerful).
To install CUDA, there are some indications in the SL forum and on that page.
