Hi,

I recently installed linux mint 18 64-bit on my new Lenovo Thinkpad 13 laptop and it works perfectly straight out of the box, except i am having trouble when connecting a second screen to it.

I first experienced the problem when i connected a second screen, the screen worked fine as a normal second screen, but when i wanted to rotate it 90 degrees clockwise so i could read some papers; it would rotate, but then the whole system would freeze up while it was displaying the "Does the display look okay?" dialogue, and the countdown timer would not count down (and after 30 seconds it didnt revert to the original settings). The only thing i could do was hold the power button down to force it to shut down and then restart.

Then when the computer booted up again, the second screen was working, except not rotated. The same thing happened if i tried to rotate it again.

A similar thing happened when i was trying to teach a class the next day. I connected the laptop to the classroom projector via the HDMI port and it worked fine as a second screen, but when i went to try and mirror my main screen, it either froze up on the "Does the display look okay?" dialogue, or it would appear to work and let me click "Keep this configuration" but then freeze up a couple of seconds after that - different times it did different things, but it would never work as it was supposed to..

after playing around with it some more, the problem seems to occur whenever i try to mirror the screen or rotate it on any screen/projector attached to the HDMI port..

Does anyone have any idea what could be the problem? I recently upgraded from my old Lenovo x131e running Mint 17, and never had any problems like this with the old computer/installation..

Any help would be appreciated, and let me know if you need any more information. Thanks

What type of graphics card(s)?
What drivers are in use?
Can you SSH into laptop when it's frozen?
Is there anything in Xorg log relevant to freeze?
Is there anything in dmesg relevant to freeze?

Hi, thanks for your reply, sorry it took me so long to get back to you.

It is just the onboard graphics card for the laptop, the output of lspci is:

the output of lshw -c video is:

not sure if it is relevant or not

i hope that gives you some more information. let me know if you need anything else

thanks again for your reply

is there anything there that you can see that might help?

It also happens when i use the FN-F7 function that switches between display modes, as soon as it gets to the mirror mode, it will freeze up and i have to hard reset..

There is Intel driver version in Xorg log, make sure you use the latest. You may want to open a bug at https://bugs.freedesktop.org/
