need help configuring x on Ubuntu 16.04

[Brian Martel]

Hello,

I’m taking care of two systems featuring dual installs of Windows and 
64-bit Ubuntu 16.04 LTS. However, one of these Ubuntu systems crashed 
with the message “Fatal error: No screens found.” I can boot up in 
failsafegraphic mode, but that doesn’t fix the problem permanently.

This system is a Toshiba Satellite C55-B5101 laptop, the specs for which 
list the graphics card as the Intel Z36xxx/Z37xxx Series, though system 
settings shows LLVMpipe for graphics (LLVM 5.0, 128 bits). I don’t 
believe that drivers are the issue, as I’ve checked both healthy and 
sick systems to find that “no proprietary drivers are in use.”

I’ve searched for similar problems in forums, and found a few. This is 
commonly a problem with the xorg config file. On both of my systems, 
rather than /xorg.conf/, /theconfig file is x//org.conf.failsafe/. It’s 
found in ext/x11. I have log files to search for clues, including 
/xorg.0.log/as well as /xorg.fa//ilsafe.log/. The failsafe log states 
that the config file lacks a Layout section.

Would it be advisable to edit the config filemanually? I’ve tried 
generating a config file by running /X -configure/, but had no luck.

Would anyone have some suggestions for me? I’d greatly appreciate the help.

Thanks!

--Brian
