kernel.x86_64 3.9.9-302.fc19 fails to detect Intel Cedar Trail graphics capability
Last modified: 2013-07-30 09:58:34 EDT
My motherboard is an Intel D2550MUD2 (Mini-ITX "Cedar Trail" aka "CedarView" with Intel NM10 Express chipset and Intel GMA 3650 video). During installation, F19/XFCE using kernel.x86_64 3.9.5-301.fc19 successfully detected my graphics card and Acer S211HL monitor (1920x1080 22") capabilities automatically. My video driver is xorg-x11-drv-intel.x86_64 2.21.8-1.fc19.
Unfortunately, my recent upgrade to kernel 3.9.9 lost my automatically detected video (no change to the video driver). I get to a login prompt window but the screen elements containing a user list are never rendered. Even the X-Windows/XFCE keyboard seems out of order (E.g. Ctrl-Alt-k combinations are ineffective). Fortunately, power off led to a graceful shutdown.
Falling back to kernel 3.9.5 successfully restored automatic video detection.
Technical specifications for the Intel D2550MUD2:
This is probably difficult to reproduce unless you have a motherboard with the same Intel video and chipset. If the kernel folks would like me to collect information and/or run an experimental kernel, I am certainly willing and able.
Please note that I'll need some help into getting into single user mode as the F19 handbook instructions for single user mode do not seem to work (maybe I missed something?). Also, a recovery mode boot got me into the same unuseful situation as normal mode.
In order to do anything useful, I believe that I would need to get into a TTY mode of operation.

After thinking about this issue more, I'd rather pursue this with Intel (01.org) and not bother the kernel folks. It will probably require an xorg update too but I doubt if this is a kernel issue.
Pardon any distraction.
