[arch-general] Intel graphics issue
Hi, this is my first Intel graphics and the first time I can't get rid of an issue. I never experienced such an issue with NVIDIA or ATI graphics. In the upper left corner of the screen, there's a flashing line, whenever I use lower resolutions than 1152x864 at 60 Hz. With my Arch Linux I'm using 1152x864 at 90 Hz and there's no noticeable flashing line, but for the syslinux menu or e.g. a live media I need to use different resolutions at 60 Hz. If I switch from 1152x864 at 90 Hz to 1024x768 at 60 Hz, something I seldom, but sometimes need to do, a flashing line is visible when running Arch Linux, too. I posted this to an Intel forum: "Hi, in the upper left corner of the screen, there's a flashing line visible at the syslinux bootloader menu, as well as when running a Linux window manager, e.g. openbox on Arch Linux or a Linux desktop environment, e.g. Ubuntu Mate 16.10. CPU: INTEL CELERON G1840 BX80646G1840 Mobo: GIGABYTE GA-B85M-D3H CRT: LIFETEC/MEDION MD1998JB Type J91B This doesn't happen, when using the same monitor with an ASUS M2A-VM HDMI mobo and an AMD Athlon BE-2350 CPU. How can I get rid of this annoying flashing line.

How can I get rid of this annoying flashing line.
This is the currently used xorg.conf:
Does the problem persist if you remove your X config so it just runs the defaults? In my experience Intel generally requires little to no configuration to work well with X.

Hi, it happens also when booting an Ubuntu Mate 16.10 Live DVD. I'll test my Arch Linux install without xorg.conf. With my current xorg.conf only 1152x864 provides a vertical frequency
60 Hz and the issue might be related to 60 Hz.

PS: The issue also is present for the syslinux menu.
