i have tried to search on google, most of them will solved just by edit intel driver conf…
but my laptop use different driver, its xf86-video-vesa, and i coulnd’t find vesa driver configuration.
i dont know if my problem related to type of vga driver that i use (vesa)…
or should i change my vga driver, remove vesa driver and install xf86-video-intel driver?
here is my vga specs
