Don't even bother trying to use the OpenGL compositors with extended desktops as mesa can not handle anything over 2048 pixels wide, and UXA is hardly any better. Can you confirm that your issue is in trying to use an extended desktop, and a single monitor works? No, i'm using a single 20" HP 2035 monitor. I've never tried to use two displays on this system. What may be interesting is that i'm using the analog VGA connection. You have a desktop that extends from the LVDS to the VGA. Have a look at the output of xrandr, and perhaps try xrandr --output LVDS1 --off. If the LVDS is a phantom output, append video=LVDS-1:d to your kernel command line to permanently disable it. $ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1600 x 1200, maximum 1600 x 1200 default connected 1600x1200+0+0 0mm x 0mm 1600x1200 0.0* 1280x1024 0.0 1024x768 0.0 800x600 0.0 640x480 0.0 $ xrandr --output LVDS1 --off xrandr: Failed to get size of gamma for output default warning: output LVDS1 not found; ignoring It seems the problem does not come from LVDS1. You weren't using the intel driver when you executed that command, so the results are inconclusive. Of course you're right :) Here's the output after booting without nomodeset: $ xrandr Screen 0: minimum 320 x 200, current 2880 x 1200, maximum 4096 x 4096 LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1280x800 58.1*+ 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 connected 1600x1200+1280+0 (normal left inverted right x axis y axis) 408mm x 306mm 1600x1200 60.0*+ 75.0 1280x1024 85.0 75.0 60.0 1280x960 60.0 1152x864 75.0 1024x768 85.0 75.1 70.1 60.0 832x624 74.6 800x600 85.1 75.0 60.3 640x480 85.0 75.0 60.0 720x400 70.1 disabling the "second screen" left the first terminal mostly on /dev/null but that"S ok. I"ve added the bootparam and i will check after reboot. Indeed, adding the bootparam fixed this issue. Can this somehow be automated? Thank you. If you can attach the output of dmidecode, we can add a quirk so that the LVDS is no longer incorrectly detected. So long as we can uniquely identify this mainboard as being a no-LVDS variant... I assume only the baseboard is required. Please let me know if you need more dmidecode output. # dmidecode --type=baseboard # dmidecode 2.12 SMBIOS 2.5 present.

On Intel D525MW motherboard (dual core atom inside) anaconda in f19 shows only a unmovable mouse cursor if booted without nomodeset. With nomodeset, install can proceed, After install, without nomodeset Gnome3, Cinnamonn, Mate and Xfce show no desktop icons and no panels. With nomodeset, all these are shown even though X uses software rendering to display them, thus heating the processor. # lspci -nn | grep VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller [8086:a001] (rev 02) # uname -a Linux localhost.localdomain 3.9.4-300.fc19.i686.PAE #1 SMP Fri May 24 23:19:44 UTC 2013 i686 i686 i386 GNU/Linux # rpm -qa | grep intel xorg-x11-drv-intel-2.21.8-1.fc19.i686 # rpm -qa | grep x11-server xorg-x11-server-common-1.14.1-2.fc19.i686 # rpm -qa | grep mesa-dri mesa-dri-drivers-9.2-0.7.20130528.fc19.i686 # rpm -qa | grep libdrm libdrm-2.4.45-1.fc19.i686 # cat /etc/fedora-release Fedora release 19 (Schrödinger’s Cat) # dmidecode --type=baseboard # dmidecode 2.12 SMBIOS 2.5 present.

Always. More info: On the other hand, i"ve seen keyboard locked, when booting with nomodeset and , when using text interface, sometimes (most of the times?) the screen gets scrambled with coloured numbers and other chars, after typing a few lines (like user name and password). Switching back to GUI and then back to text, seems to restore text visibility. I"ll attach the other required info after rebooting with drm.debug=0x06 and without nomodeset.
