Need to know how to find and fix missing files to get GUI working again

Hi all,
I removed some kernel packages to free up some space on / and now I can not get into my GUI, I get and error "Something went wrong log out to try again" when the GUI starts. I had managed to follow this http://www.cyberciti.biz/howto/debia...y-unix-driver/and it did work before and I had a GUI. Now it tells me I have the wrong version of GCC and to specify the correct version. I have no idea how to do that.
So the short version of my question is how do I find out what got removed so I can fix this? I did have the disable-nouveau.conf file created but at boot I was getting getting messages about two tokens needed and only one found, what ever a token is.
I am using Windows to get here and have to reboot into linux. So please be patient with me and give thorough directions.

Do you remember what you removed?

In all honesty, if you are removing kernel related things you must be desperate space wise
why the space concern?

How did you 'remove'?
If it was apt-get simply 'reverse' by using "install"

Code:

sudo apt-get update && apt-get dist-upgrade

May also resolve it

sudo assumes you have 'set it up'
If not, do as root (leave off sudo)

Read your link, one of those 'not so helpful' blogs (seriously, ignore them, , they are seldom useful)

Show us the output of

Code:

lspci

A liveCD may help with copy'n'paste

Deleting /etc/X11/xorg.conf might help
At least get you to s GUI (downgraded)

I ran

Code:

dpkg --list | grep -i --color nvidia

and then

Code:

apt-get purge <package name>

until that command complained it could not connect to the repository then ran

Code:

apt-get autoremove

and then rebooted.
I was removing files to try to gain disk space. I am getting pop ups about being out of room on the root File system I am using LVM and the drive is 250 GB I would think I have plenty but apparently not.
So next question is how do I clear up some space... SAFELY?

Got it back?

I assume you got the nvidia drivers for the "gt 640" working

Yes I can login via the GUI now :D

Ahh, ok

If it works fine, leave 'as is'

But you may need proprietary drivers for 'full' capability

I haven't tested the 3d ability yet but Iain't gonna try to fix that yet. I am more worried about getting some disk space available. Any ideas on how to find a way to clear some room on the hard drive??

Get familiar with the different disk usage type commands to find out where all your drive space is going.

Code:

df -h

That will give you an idea of what your total usage is and where. You can also use commands like 'du' or 'dd' to do something similar if not exactly the same, but (as with most things in Linux) you need to do some reading and self-educating.

When all else fails, bust out some Google-Fu and search for "Debian disk usage commands". Then pick a result and start reading.

I like ncdu
http://dev.yorhel.nl/ncdu
Probably available via your package manager

There are gui equivalents available, but I find them to be slower.

hmm it would appear there is a bug in the disk usage analyzer tool, it pops up warnings about being out of disk space but if I run

Code:

du -hc /

it shows that i have

Code:

20G total

which tells me I have only used 20 GB of a 250 GB hard drive :(
I can't post the complete output of the command because the output is over the limits of this web page.

20gb seems reasonable

Output of

Code:

df -h

Will help

ncdu is not so easy to cp'n'paste

But, 20gb seems about right

20 gigs is all right depending on what has been installed to system & how many /varog messages there are. I have seperate /usr & /var & the /usr & / have had to be resized.

Speaking of things like log files, have you tried either

Code:

apt-get clean

Code:

aptitude clean

? Lots of installing and removing of packages can fill up the the root directory with "residual" files. (I chose residual, because I do not know the proper word.)
