I have an AMD a10-5800k APU that I was using for graphics because it has integrated graphics. Knowing that I can't use AMD Dual Graphics on Linux, I got a dedicated card anyway because I can use Dual Graphics in Windows. Even though Windows is better for gaming now, Ubuntu is not only slow now, it's become terribly unstable. Even the keyboard is acting odd.
Information that may help: the GRUB bootloader is now in a low resolution like 800x600 or 640x480, not sure which, whereas it used to be in 1080p like the desktop. The Ubuntu splash screen is gone so after grub the only visual that comes is the login screen. After logging in, the background becomes completely jumbled before the launcher loads, after which it stabilizes. Very noticeable keyboard input delay now as well.
Is this a bug or can I fix it?
