After changing my main username after this tips, my Lubuntu laptop is only starting showing me only a dialog, that sais, it is in low-graphics mode with only one button "OK" and then a menu opens up with some options, but there I cannot select other than the first option:

What would you like to do?

[x] (Try running with default graphical mode)
[ ] (Reconfigure graphics)  
[ ] (Troubles boot the error)
[ ] (Exit to consol login)

                                    ([cancel] [ok])

I can reach cancel and "ok" with the TAB key, but I tried all combinations of TAB, arrow keys, enter, space and pg up and down to select another option than the first, but nothing worked. Also attaching a USB mouse makes no difference.

How can I reach the option "Reconfigure Graphics" ?

Note: I am leaving this question open, although I've already recovered from this low-graphics-state (see my answer below) and there are many options How to fix "The system is running in low-graphics mode" error?. It still would be interesting, how to change the selected option in that dialogue, when it seems not possible.

Try boot at recovery mode, low graphics, and choose"resume" option, after login, go-to settings/display and turn off every monitor not in use...

  • The recovery mode is not possible in the main grub selection, I had to choose "Erweiterte Optionen", there are the recovery mode kernels to start see this manual) – rubo77 Jun 29 '17 at 05:54
  • Anyway, This is not really an answer to the question. I asked, how I can select one of the other options (that might help me) but it is not possible to select them. that is my problem here. – rubo77 Jun 29 '17 at 05:56
  • I tried recovery mode and chose resume, but this didn't help. It starts with the same low-graphics mode and nothing else to do there. I also tried "failsafeX" mode – rubo77 Jun 29 '17 at 06:02
  • After resume, login, and settings/display and if more than one monitor, turn off monitors not in use, then restart normal... Is there only one built-in monitor, or more than one? – joao Jun 29 '17 at 16:39
  • only one built-in monitor. And I cannot login! I just get this low-graphics box, and if i close the box, it just comes back. I cannot loginto the desktop at all – rubo77 Jun 30 '17 at 13:37
  • I would like to select "(Reconfigure graphics)" but I cannot klick on it, that is the problem. there is no mousepointer – rubo77 Jun 30 '17 at 13:38

    The solution, in my experience, does not work with reconfigure graphics. I would install cssm and enable unity, because if no login then unity is disabled, and no other desktop is installed by default – joao Jul 03 '17 at 14:48

The solution to get rid of the low graphics warning was to install ubuntu-desktop over Lubuntu:

sudo apt-get install --reinstall ubuntu-desktop

When those were all installed, the Low-Graphics warning was gone, so I will never find out, how I could have reached the other options though.
