Overview: On notebook with switchable graphics (Acer Aspire 4820TG-5454G50Miks) when switching to the integrated graphics card before starting Xorg server, system usually shows non-blanking cursor and hangs up.
Steps to reproduce:
- Switch to the integrated graphics card with vgaswitcheroo (with or without switching off unused card)
- Start Xorg
System hangs up.
Xorg starts properly, login screen is shown.
Repeats with current stable version (2.14.0) and with older commits, also with older driver and Xorg versions on Gentoo Linux (~amd64 + x11 overlay)
