After booting the screen on my Samsung ATIV 940x3g Ultrabook with qhd+ display
remains most of the time off.
Usually two or three reboots solve this for one session and once the desktop is
up there are usually no Problems. However having to reboot several times to get
there is not convenient.
The OS is standard Ubuntu 13.10 up-to-date (10.3.2014)
The graphic package versions are:
ii intel-gpu-tools 1.5-0intel2
amd64 tools for debugging the Intel graphics driver
ii intel-linux-graphics-installer 1.0.4-0intel1
amd64 Intel graphics drivers update utility
ii libdrm-intel1:amd64 2.4.49-2
amd64 Userspace interface to intel-specific kernel DRM
services -- runtime
ii libdrm-intel1:i386 2.4.49-2
i386 Userspace interface to intel-specific kernel DRM
services -- runtime
ii libva-intel-vaapi-driver 1.2.2-1
all VAAPI driver for Intel G45 & HD Graphics family
(transitional package)
ii xserver-xorg-video-intel 2:2.99.907-0ubuntu1
amd64 X.Org X server -- Intel i8xx, i9xx display driver
Linux version 3.11.0-18-generic (buildd@toyol) (gcc version 4.8.1
(Ubuntu/Linaro 4.8.1-10ubuntu8) ) #32-Ubuntu SMP Tue Feb 18 21:11:14 UTC 2014
The CPU is:
model name : Intel(R) Core(TM) i7-4500U CPU @ 1.80GHz
In the attachement are the follwoing logs:
xrandr
dmesg
intel_reg_dumper
Xorg.0.log
The logs were generated when Ubuntu booted up nicely
If required I can make a Video on the bootup problem and upload it.</pre>
