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) :

sorry if i did respond too late ! thanks i will look into links if the problem gets solved i'll notice u.

I have the same exact notebook computer which exhibited a scrambled display when I tried to install both Debian and Devuan. Screen scrambling still occurs as soon as the Linux kernel boots, although Windows 8.1 does not exhibit any similar problems. I do not remember what workaround I used, as I have been using several workarounds to install Linux these last years. Probably, I used debootstrap running from within a live Ubuntu or Debian instance. Even Devuan made installation difficult with the 'infamous' disk formatter obliging me to use LVM which I refused.

An archive containing the directory tree and contents of the entire base system as installed by debootstrap plus a basic /etc/network/interfaces and a password set for root , would be most welcome, but don't expect that to happen. Linux relies on installers, and the latter rely on properly initialised/identified hardware.

Lately, I was told to buy an asus laptop for their Linux support. However, their decision to solder part of the RAM to the motherboard, is something I want to get away from. RAM has the bad habit of failing before a motherboard or CPU fails.

so u mean that there is no other way rather than using debootstrap?
