The resolution change is likely the result of Kernel Mode Setting (KMS). This is the ability for the linux kernel itself to set the resolution of the display, among other things.
The easiest way to turn it off is to add "nomodeset" to your kernel commandline.
The correct term, by the way, is not "text mode", but rather "a virtual console" or "virtual tty" or such.
Hopefully that gives you enough search terms to learn more.
- JdeBP 9y agoActually, the correct term is text mode. It is precisely whether the display hardware is operating in text mode or graphics mode that is the subject of discussion here. With the hardware in text mode, even without CRTC tricks, scrolling is relatively fast compared to graphics mode. Scrolling the display in graphics mode involves shifting much more data around, as does rendering individual characters. The confusion arises because people, as you have done, erroneously conflate the kernel virtual terminals with "text mode". In fact, the norm nowadays is for kernel virtual terminals to use graphics mode. It permits a far larger glyph repertoire and more colours, for starters, as well as things like software cursors that can be a wider range of shapes and sprites for mouse pointers.
