Hi,
Thanks.
After I changed the Mate Tweak to HiDPI, the things were from annoying (different thing sizes in the two monitors) to very bad.
The only change in the system before this was the Mate-Tweak 'auto-detect' to 'HiDPI'.
1- The computer now only starts in the 'recovery mode';
2- With 'HiDPI', first thing, the compute didn't detect the 2.nd monitor if I start with it disconnected. If I start with the 2.nd monitor connected, the system uses it as main one and don´t recognize the build-in monitor;
3- With 'HiDPI', and only the build-in, the things in the screen are absurdly big
4- Changing back Mate-tweak to 'auto-detect' did not return the thins as before. The computer don´t restart unless using the recovery mode. It finds one or other monitor, never both. The Build in has wrong resolution and no option to change in in the settings.
Very frustrating!
How can I recover the previous setting conditions? Or need to start from scratch the system installation? Or how can I fix this using the terminal!
