Hello, LQ.

After having some software installation issues on Wheezy, I decided it was a good idea to go and upgrade to Jessie. I have encountered issues since then.

(I apologize in advance for any improper usage of the linux lingo.)

Here is my situation: after the update I mentioned earlier, when I booted my computer back up, I lost my graphical log on screen, and instead have a text based one (?) with "Debian GNU/Linux jessie/sid Computer tty1" at the top. When I log in, I am greeted with a command prompt. I believe the issue is because of the driver incompatibility between Wheezy and Jessie, particularly with my graphics driver and my WIFI driver. I could be completely wrong though. I say this because I have tried installing new graphics card drivers, but aptitude doesn't seem to connect with the web. I don't know where to begin with installing these drivers (if that is the issue), or if I am even headed in the right direction.

Thank you in advance for your help.

Hi,

you likely have an /etc/X11/xorg.conf that is configured to use a propriatory driver that was not upgraded when you did the upgrade to Jessie. This is would be why you are not gettting a gui now. If you are using networkmanager to configure your network, then I think the network will not be configured unless you start the graphical environment.

So to get the graphical environment and hence the network back you should try to use the free graphics driver that your system already has. This may be as simple as moving your config file out of the way. Eg as root
And then trying to restart X (or just reboot).

PS. There are lots of useful diagnostics information that would help in understanding the underlying problem (log files hardware listings etc), but since you don't have a gui or network you may struggle to provide this information. This is why I've suggested the approach above.

Thanks for the reply.

It's good news that the network isn't configured because because of the graphical environment. That should mean I only have one driver issue, right?

I typed the command you suggested into my prompt as root, and after rebooting, still no graphical environment.

I could definitely provide photos of the log files, if need be.

Hi,

ok the file we need to see is /var/log/Xorg.0.log. You can display it with the following command:
You can scroll through it with the arrows or pgup/pgdn, q to quit. If there is too much to photo graph and post you can show just the errors and warnings with:
It is also worth confirming when the file was written. You can do that with
Evo2.
