Re: How does this help?
I haven't been using Linux for 20 years, it's only about 8-9 years, yet I know enough of resolution setups though to resort to the xrandr command. In your example, a text buffer driver is set up for a high resolution. Only technically adept person would most probably need it. Hence it must have been explained that way. On the other hand, why would you need a 1366x768 resolution when booting?
As far as the video driver is concerned, it's xrandr, if not automatically probed.
If the video drivers is capable of the needed resolution, and the grandr, gnome-/mate-monitors isn't able to probe, xrandr might still handle it.
Here is what I just did for 1360x768 on my old i915:
gtf 1360 768 60.0
xrandr --newmode "1360x768_60.00" 84.72 1360 1424 1568 1776 768 769 772 795 -HSync +Vsync
xrandr --addmode VGA1 1360x768_60.00
xrandr --output VGA1 --mode 1360x768_60.00
And you got that resolution!
It's a copy-paste stuff and has much more sense than "clean your computer from viruses, clean the Windows registry, reinstall Windows etc"
I myself learned most of what I know about Linux, Unix, FreeBSD and other IT related things from the forums, yet never did I have to ask a single question there. Someone did it for me and before, so I just used it to learn a lot of stuff. I did try helping other as well and followed the tradition of doing that in a user friendly manner, as well as reported a few bugs, having found and published some resolutions and workarounds. Well, the Linux forums are usually the most user friendly and unassuming. FreeBSD ones are most cryptic and concise, yet highly informative. While, my Windows forums experience is much much worse.
