Dear Debian community,
For the Lenovo T440s laptop, I recently aptitude upgraded libgl1-mesa-glx from 13.0.6-1+b2 to 17.2.2-1 and rebooted. Now startx returns
xf86EnableIOPorts: failed to set IOPL for I/O (operation not permitted)
Couldn't open libGL.so.1: /usr/lib/x86_64-linux-gnu/libGL.so.1: undefined
symbol: _giapi_tls_Current
xinit: giving up
I filed a bug report here https://bugs.debian.org/cgi-bin/bugrepo ... bug=879583, but currently the laptop is unusable. What can be done to temporarily regain usability of the laptop? Note, a computer that could not upgrade libgl1-mesa-glx due to dependency conflicts with nvidia drivers works fine.
Thanks,
Paul.
