Does ubuntu work on the 4k display? I'm planning to buy lenovo thinkpad laptop with 4k screen. But I have concern about whether scaling works as expected or not.
I have a modern Philips TV with Android (it's connected to my local network). I can simply cast the screen of my Android phone but Is it possible to use TV as the second monitor for my laptop with Ubuntu 20.04 via wi-fi?
I'm planning to upgrade my PC and I'm considering buying a PCIe SSD drive and booting from it. I've read there was a problem booting with some PCIe drives. Is it possible?
- My motherboard: GIGABYTE GA-X58A-UD3R (rev. 1.0)
- OS: Ubuntu 19.10 x64
I have a Dell Latitude 7400 and want to install Ubuntu 19.04. When in the install menu, I don't see its SSD, only my current USB drive. Windows 10 is installed on this laptop, but I don't see it. What could be cause of this problem?
Please look at output:

I try to read log file by deploy user:
deploy@li445-201:~$ cat /var/log/nginx/access.log.1
cat: /var/log/nginx/access.log.1: Permission denied
Why I can't read log file? I've set even 777 permission on it

During my work I need to set up many tunnels. What is the best practice to manage it? Sometime tunnels can lost connection I want to auto reconnect it, maybe there is good thing to do it automatically

Can I resume Ubuntu after suspend by shortcut from keyboard?
I have a docking station with thinkpad and an external monitor. My laptop is always closed, so I need to open it and close again to resume system, it's annoying.
Sometimes my system (Ubuntu 14.04 64bit with the latests proprietary drivers from repositories) hangs, artefacts appear on the screen and systems doesn't respond on any commands from keyboard or mouse. I connected to my machine with ssh and run dmesg, output:
[100002.771845] NVRM: Xid (PCI:0000:04:00): 6, PE007e 00dc 00ffffff 00000000 00000000 00000000
[100002.773784] NVRM: Xid (PCI:0000:04:00): 6, PE007e
[100002.775644] NVRM: Xid (PCI:0000:04:00): 6, PE007e 00dc 00ffffff 00000000 00000000 00000000
How to fix this problem? I tried use nouveau, but in this case suspend doesn't work.
After restart computer global menu in nautilus disappeared.
