So you're saying that lxrandr is not included in LM12 lxde?
- Silly me... what is it then that controls the monitor settings in Mint lxde?
By the way - booted into recovery mode, entered "terminal" (or whatever it's called) and called up lxrandr and xrandr respectively, and both of them returned an error - think it said "can't open screen". Don't know if this say something.
Even so... forgive me, but I'm not sure you read my post completely. I can log in, but then the screen goes black. How am I then supposed to install lxrandr? (now that you say I don't have it) I'm in a hotel room, with a wireless connection. Are you saying that I can go into recovery mode, log in to a prompt as root with network and download & install lxrandr?
Besides - I didn't have any problems using both internal/external monitor (or one at a time) at home. It's just that for some reason I forgot to switch back to internal monitor only while the external was still connected. (Don't understand why my OS doesn't understand that one monitor got disconnected). So - knowing that it actually does work with two monitors already - why would I have to download and install something new.
Finally - a side note:
With all due respect - I understand that you're proud of your guide, and therefore like to promote it - you should be proud, because it is a damn good one. But please understand - and no disrespect meant - this is the second time you answer one of my questions with a link to your guide, and while it is a good one (said that already didn't I?) it doesn't really answer any questions just posting a link. Moreover - for someone asking a question it might not be of any help at all just getting a "RTFM" (I know that this is not what you mean, but that is how it can be interpreted) - it ain't that simple. The first time I got the link as a reply the answer wasn't even close to be being found in that guide, becasue it was my own stupidity confusing one applet with another that created my problem. So would it hurt to actually try to look at the problem and answer accordingly instead of just throwing that link around?
1. Seems I do have lxrandr already. Hope it came by default, because I can't remember installing it (on the other hand - I am getting older, so that might be the explanation.
2. The error I get when trying to run lxrandr or xrandr from the "prompt" is : "Can't open display" - nothing else.
3. Tried running sudo X -configure (read that somewhere in these forums.) That one ended with: "Number of created screens does not match number of detected devices. Configuration failed."
