As I could barely read the small letters with the HD / 1920x1080 resolution, I choose to reduce the resolution.
I changed it from the display settings from 1920x1080 to something like 1360x786 or so.
I clicked apply system wide, and apply.
After a reboot, I get the login prompt. When I login, the screen goes blank and stays blank.
How can I restore the original settings, or boot to rescue mode, or reset factory defaults, without having the GUI? From the console prompt? Or any other option?
ho lo stesso problema

Hi tophneal,
how to adjust HiDPI scaling? I can't find it...

Hi,
did you mean that changing these lines, I can set a 1024 resolution ?
<width>1920</width>
<height>1080</width>
<rate>59.99</rate>

no. resolution must be FHD. you can use scaling to get the desired effect.

ok, perfect,
but I don't know how to set scaling...
where should I go?

If you haven't already, install MATE Tweaks, and the scaling options can be found there.

I was really unhappy when I realized I couldn't change the resolution. For me, the real life saver was the Zoom Page WE extension to firefox. From that time, I like this little device. I can set up default 150% zoom for every page. Now I don't have problem with readability. Cool !

I'm fiddling with a pair of progressive reading glasses, I can actually boot to a console and read the text, if I need to. in Firefox you can also do ctrl-+ to zoom. But I'd like about a 1366x768 mode.

Not always, depends on version,, in vt, tty
setfont -d
When it works, really easy
(works with manjaro)

Everyone should be clear. Changing resolution in ANY LCD on ANY device, (Phone, Tablet or Laptop), is problematic and likely not what you want. LCDs, (and possibly other tech like plasma), are digital unlike the old analog cathode ray tubes of last century.
The only slight exception to this, is specific integer reductions. For example taking 1920 x 1080 to 960 x 540. And that is only dependent on the LCD monitor supporting such.
Using anything else, (assuming it even works), will lead to fuzzy screens. The amount of fuzziness depends on the graphics card, the LCD and the content to be displayed. So, if you don't see any fuzziness, that does not mean you have a solution. Just means with that specific combination you don't see it.
In the case of desktop LCDs, they kinda have to support odd / non-native resolutions. This is because you need something to actually use the computer, to get to a LCD native resolution. For example, some computers boot to VGA resolutions of 640x480 or 800x600. Neither of which are integer reductions of most higher resolution LCDs. Whence the computer is done booting, the OS takes over and sets the graphic card's output to the LCD's native resolution.
Everyone with vision problems, whether minor or major, (and this includes ME), should set the OS user interface to support their needs. We created a section on the Wiki for thus purpose. It's vague, because it's GUI dependent. Feel free to add details for a specific GUIs.

I'd rather have a high resolution monitor, and make the items in it, (be it text or icons), larger. Than less resolution. This is because letters and icons with more detail, are easier on the eyes, which makes them easier to interpret. Even if you have to make them bigger.
