The other day I posted a topic saying that after installing CentOS (and then Redhat 7.1) on a usb pen drive, the OS would work on my HP desktop but not on my ThinkPad. On the ThinkPad, the OS would freeze after logging in. It worked ONCE but then started not working again.
So I searched for some answers, and one person said he cured a similar problem by updating his nvida drivers from RPMFusion (but damn if I know how to do that..I really am a linux novice..)
Another person said he got around the problem by starting the OS in text mode, logging in from text mode, and then issuing the startx command. THAT approach seems to have worked for me, so I just wanted to share what I did to get this to work.
While on my HP, I issued the following command from the CLI:
systemctl set-default multi-user.target
This made it so that every time I boot from the pen drive, I automatically go into text mode.
Then after booting and going into text mode, I log in from there, and then issue: startx
Voila! I get the gui back and I am IN and working. And no freezes so far.
As work arounds go, it's not too bad!
At any rate, I just wanted to share this information with the group.
