I have Ubuntu Server 18.04. I installed Xorg, plugged in my monitor and started my app like this:
startx ./MyApplication
It runs perfectly, but if I unplug my monitor, run the command and then plug my monitor again, Xorg cannot detect the monitor.
Is there any solution for this? Can startx auto detect the monitor? If not, should I use something else, like Wayland?
I have written a code to display some images with golang and SDL2, I have tested the code in the Ubuntu desktop 18.04 and had no issue. I wanted to use the code in an embedded configuration, and wanted the OS to run the code automatically on start up, the Ubuntu desktop has a lot of bugs and many times it hangs on the login screen, so I decided to use the Ubuntu server. My problem is that the code in Ubuntu server can't create any window to show the images. First of all I wanted to know what packages should I install to be able to run SDL, secondly, my monitor and images are 4k, can that also make some trouble?
I have installed ubuntu 19.04, and it won't boot without HDMI connected, I have tested Ubuntu 18.04 and it has no problem, so it shouldn't be from bios. Any ideas?
I have boought 4 asus mini Pcs and installed ubuntu 18.04 and some required packages and libraries I needed. My problem is, One of them freezes on boot, it was ok at first but after some restarting, it became faulty, I thought maybe the problem arises from hardware, but I installed windows 10 on it and it booted successfully. How can I find the problem. If it's a hardware issue, how can I make sure? The mini pc is ASUS pn40 with 120gb ssd and 4gb ram.
I have a compiled file written with golang, if I transfer the file to another PC with a usb driver, and add the permission with sudo chmod +x myfile, it runs perfectly, but when I transferr the file with filezilla and do the same process, it says: can not execute binary fil: exec format error, Why is that?
