After upgrading to Ubuntu 17.10 my secondary screen cannot be detected anymore. I have an AMD Radeon HD 7700M card and my monitor is connected through HDMI or DisplayPort, neither connection works. In Ubuntu 17.04 I had the possibility to revert to an older kernel and then it worked, but now even that older kernel is not working anymore.

@MichaelBay, that driver does install but gives me a blank screen. – Wilko van der Veen Nov 03 '17 at 09:14

I'm having a similar issue with my laptop which has an AMD APU. Total dealbreaker for me. I need an external monitor to work. Digging around for a solution... – CptAJ Nov 08 '17 at 01:17

I have a Nvidia 340 driver for my G92 GeForce GTS250 graphics card. I had the monitor not detected the problem after a kernel upgrades from Kernel 4.10.0-42. I just tried out the open source driver and I don't know why but it works and I can get the full-screen showing. Before I had a big black band around the display. I don't know what problems I will have with the open source driver but if nothing serious goes I have to use it or go back to an older kernel. I am using Linux Mint 18.3. This is only a a possible work around if the original driver is proprietory. The open source doesn't take advantage of many of the features of the graphics card I understand. For my purposes I have a functioning monitor.

I regret to say that I too am confused. You seem to imply that the open-source driver fixes the problem that occurred with the display. If this is the case, then you haven't actually posed a question. And, this forum is only for questions related to Ubuntu. Questions relating to Linux Mint should be posted at https://unix.stackexchange.com or https://forums.linuxmint.com – CentaurusA Sep 01 '18 at 01:35

Welcome to Ask Ubuntu! I recommend to [edit] this answer to expand it with specific details about how to do this. (See also How do I write a good answer? for general advice about what sorts of answers are considered most valuable on Ask Ubuntu.) – David Foerster Sep 01 '18 at 02:13
