I recently switched to ubuntu 16.04 on my laptop which is a thinkpad P51. I am having the issue that sometimes the login desktop freezes in the sense that I am able to move the cursor and interact with the desktop but nothing will run. For instance I can shutdown but it will not shutdown and seems to just freeze at that state, at many points in time, I need to force shutdown. I am not sure what the problem is or even how to go abouts debugging it.
I have posted a picture of what it looks like on the login page:
I am using kernel version 4.10. The specs for my computer are as follows:
-Computer- Processor : 8x Intel(R) Core(TM) i7-7820HQ CPU @ 2.90GHz Memory : 65684MB (2271MB used) Operating System : Ubuntu 16.04.3 LTS User Name : johnz (johnz) Date/Time : Sun 07 Jan 2018 01:21:34 AM EST -Display- Resolution : 3840x2160 pixels OpenGL Renderer : Unknown X11 Vendor : The X.Org Foundation -Multimedia- Audio Adapter : HDA-Intel - HDA Intel PCH -Input Devices- Sleep Button Lid Switch Power Button AT Translated Set 2 keyboard Video Bus Video Bus SynPS/2 Synaptics TouchPad Microsoft Microsoft® 2.4GHz Transceiver v9.0 Microsoft Microsoft® 2.4GHz Transceiver v9.0 Microsoft Microsoft® 2.4GHz Transceiver v9.0 TPPS/2 IBM TrackPoint Integrated Camera ThinkPad Extra Buttons HDA Intel PCH Mic HDA Intel PCH Headphone HDA Intel PCH HDMI/DP,pcm : 3= HDA Intel PCH HDMI/DP,pcm : 7= HDA Intel PCH HDMI/DP,pcm : 8= -Printers- No printers found -SCSI Disks- ATA Samsung SSD 850
When I check xsession-errors, it has the following message:
openConnection: connect: No such file or directory cannot connect to brltty at :0
This is quite annoying because everytime i need to force shutdown, and I would really like to fix this. I would greatly appreciate any help.
