I use Ubuntu 15.04 and Windows 8.1 (native) on a Medion Microstar AkoyaE6239. I started with Ubuntu 14.10 and then updated it.
The problem I describe here also happened in 14.10, and I tried to solve it, but somehow, after some days, I started the PC and the problem disappeared for no apparent reason.
Yesterday, while using Ubuntu, it suddenly shutted down, and when I rebooted it I had this problem after selecting Ubuntu in the GRUB menu:
First it says
error: invalid mode specification "text". booting in blind mode
and then the command line interface appears with this error:
(My screen is also broken, so I can not type all the error parts. the "[...]" parts are these parts. Sorry.).
[ 1[...]995] ACPI PCC probe failed. starti[...]rsion 219 [ 12..[...]2] intel_soc_dts_thermal: request_threaded_irq ret -22
Then the purple Ubuntu graphic loading splash image starts checking filesystems, it says this:
Press [...] cancel all filesystem checks in progress Checking [...]gress on 1 disk (6.1% complete)
And then it goes back to the CLI, like this:
[ 1[...]995] ACPI PCC probe failed. starti[...]rsion 219 [ 12..[...]2] intel_soc_dts_thermal: request_threaded_irq ret -22 Welcome to [...]mergency mode! After logging in, type "journalctl -xb" to view system logs, "systemtl reboot" to reboot, "systemctl default" or ^D to try again to boot into default mode. Give root password for maintenane (or type Control-D to ccontinue):
This is the error. I can log in and use the system, but only in the CLI, I try "startx" and it fails to start. I have checked the output of "journalctl -xb", but I understand nothing, as I am a novice Linux/Ubuntu user.
Here is the journalctl -xb
output from yesterday.
What could I do?
Thank you very much,
