as in topic subject - I switched from Jessie to Wheezy(by commenting out #! repos and changing all "wheezy" to "jessie".
After reboot, I can't use GUI.
I have 2 different kernels, one will load GUI, but after logging in nothing happens, and in second one GUI won't load.
Any ideas or questions for additional information? It's quite urgent...
If you are willing to help me right now, you can join #! help IRC, I will be here for ~2 hours at least.
Thank you in advance.
