Intalled the wrong driver

Post by micahh2 »

After a power outage my computer's resolution was out of whack (I mean to low) and it wasn't working the way it should (going to display settings didn't help) I installed a ATI drivers for my graphics card, don't ask me why I was just experimenting, while I have learned my lesson I now cannot boot up mint, well I can but I get a messed up screen. Do I have to reinstall?

I think its was supposed to have nviada dirver installed

I believe this is the relevant output from the lspci command:
VGA compatible controller: VIA Technologies, Inc. KM400/KN400/P4M800 [S3 UniChrome] (rev 01)

really sorry, it was a quite dumb move, maybe this post should be in novice advice

You have Via Unichrome - not the most easy to cope with
There is a driver installed by default - openchrome
I don't understand how you managed to install the ATI driver, but try to uninstall it the same way you installed it
Then edit xorg.conf

Code: Select all

gksu gedit /etc/X11/xorg.conf
Add a line
Driver "openchrome"
to
Section "Device"
Hopefully this helps

um well you see I cant boot up actually I can I just cant get to the boot screen to get to the terminal. when I boot up i get the nice Linux mint logo wit the loading bar then the screen turns black for a while and I get a garbled red blue and black screen from which nothing I do seems to make a big difference, some key combinations change the red black and blue screen a little bit, but not much. :oops:

If it helps I guess the first time after I made the mistake I tried to boot up and it dropped me right in to the terminal where I proceeded to login and type:

Code: Select all

sudo kill now


It said the system is shuting down now! for maintenance

and then I got a red blue and black screen giving me many options among them "fix graphics" (or some thing like that) and normal boot

I chose fix graphics hoping that it would reset the driver, the next time I boot up well I get what I described above.
I hope you can help you guys have great support and a great OS :D

Okay update, for some reason I was under the impression that I was unable to boot into system rec I am able to boot into sysem rec and I think I might be able to fix my problem, by uninstalling the ati driver then installing the right driver (opencrome), If I can drop to root, therin lies the most recent problem, it wont acept my password for root I have tried it many times and it wont let me in. I haven't set a 'root' account up since it was advised against when I set up the operating sys, could this be the problem?

Also this is how I installed (by accident) the ati driver.

Code: Select all

sudo envyng -t
and then

Code: Select all

3

I know it was dumb but maybe some one else can learn from this.

If you have Gloria the root password is the same as your password
In earlier versions it's random unless you set it yourself
Boot the live CD
Edit /etc/X11/xorg.conf in your installed system on the hard disk
In Section "Device" add the line
Driver "vesa"
Reboot and you ought to boot normally, but vesa is a crappy emergency driver
Delete the Driver "vesa" line
Proceed to uninstall the Radeon driver through Envy and reboot
I think you should be back to normal
If not try adding the line
Driver "openchrome"
the same way as before if necessary

I'll give it a try thanks! but for those who might have had a similar problem (with booting into root, not installing the wrong drivers) I updated to Gloria but maybe it didn't reset my password?

Yes - upgrading to Gloria does not give you the Gloria behavior for root password
It can't be done I think so when you're up again set a root password
