dell monitor

Hello all. Has anyone tried to get a Dell Ultrasharp U2415 monitor to work with Linux? I searched the forums but nothing turned up.

Thanks for your inputs

intel i56500, asus h170 pro gaming, 8gb

Please give a better description about your problem. Doesn’t it show anything at all? Do you get no graphical, but a CLI login? Does it work, but in the wrong resolution?

We are realy not able to look over your shoulders and depend completely on what you describe.

Thank you for your reply. At first try, I connected it by DP cable. It powered up and displayed the message No DP Cable Found. I didn’t have a manual at first since they supply all documentation by windows CD and I’m Linux only. The message floated around the screen without a cursor showing. Then I tried a HDMI cable but got the same result but the msg displayed No HDMI Cable Found. I found the PDF manual online later. The floating msg is DELLs test routine. Connect the cable to the monitor but not the computer and power it up to test it. The floating msg shows that the monitor is working correctly. I’ve been searching for help online but finding almost nothing for this monitor. Related ultrasharp monitors in the 2400 line have worked out details online but this one does not, not that I can find. I found where people have gotten the ultrasharp 2715 to work with Linux. I found a couple reports of people getting the 2415 to work but that was with Ubuntu. I found a vague thread where someone says that it requires kernel 4.3 because of needed drivers. I’m stuck at this point. I couldn’t find anything in the forums or in opensuse documentation. Maybe I picked a monitor a little too new? Sorry for the vague first thread but initial searching turned up almost nothing and I didn’t have the manual.

Did you get it to work? I am facing a similar issue with a brand new Dell Ultrasharp U2417H. I bought a mDP to HDMI and a DP to HDMI cable but neither do anything whatsoever on my Linux laptop. The screen says that nothing is plugged in.

So for some reason is seems the connection only works if using an HDMI to HDMI cable. I read on an Ubuntu thread that it could be due to a sync issue between the DP and HDMI connectors.

For reference, here’s my configuration:
ASUS Laptop with a 4K screen
Dual graphics: 00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 06) and 02:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 960M] (rev a2)
Running the “nouveau” driver.
