I have just upgraded my Lenovo T530 laptop (Intel HD 4000 graphics) from 14.04 to 16.04.
I can open text windows (Ctrl+Alt+F1 etc) but despite trying lots of things, can't get any graphics.
System worked perfectly with 14.04, and can also dual boot to Windows 7, which still works OK.
I have tried reinstalling the drivers:
sudo apt-get install --reinstall xserver-xorg-video-intel xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg
This made no difference. I have also tried things to do with the resolution to no effect (though that was rather random, I wasn't very clear what I was doing).
I get the following error message during the boot process:
[FAILED] Failed to start Load Kernel Modules.
See 'systemctl status systemd-modules-load.services'
I can't see anything in systemctl to explain the problem though I don't know what I'm looking for.
I've looked through a lot of log files and not found much. Xorg.0.log includes the lines (truncated a bit to save typing)
AIGLX error: dlopen of .../dri/1965_dri.so failed (.../dri/1965_dri.so: undefined symbol: _glapi_tls_Dispatch)
AIGLX: reverting to software rendering
AIGLX error: dlopen of .../dri/swrast_dri.so failed (.../dri/swrast_dri.so: undefined symbol: _glapi_tls_Dispatch)
GLX: could not load software renderer
GLX: no usable GL providers found for screen 0
Obviously something isn't loading, but I'm not sure what or how to fix it. Any help greatly appreciated.
