issue with installing debian
Posted: 2017-05-05 16:44
hi guys so sorry if i didnt make a correct topic in the right place or something . well i have a weird issue with installing debian on my laptop. the model is hp probook 4540s ( which is using switchable graphics) . the issue that i am having is called something like scrambled screen. i didnt find any source for this issue on debian but i saw something which was for ubuntu. the issue seems to be existing on every debian ver8 or higher when i try to enter graphical installer or even the normal installer.

At first, i thought it might be from the switchable graphics but it had no difference with disabling the second graphics.
i tried to switch the boot mode from uefi to legacy but still the same.
after some research i just found some bug report about this issue ( which unfortunatly not solved ) and some one had the same issue on a lenovo device.
i think it should be from the graphics because the keys work on installer and only the screen is not showing things properly.
i thought i could do something with the console but when i try to access console ( using ctrl+alt+f1 to f5) :
