In this post, we are going to see how to easily set up our LXD installation in order to be able to launch on demand containers that we can run GUI apps in them. Now to find where the color profiles are stored! OH WAIT I can set colors right on the monitor with BUTTONS unlike these new flat screen things where you can’t adjust anything at all without being some sort of genius programmer.How to run graphics-accelerated GUI apps in LXD containers on your Ubuntu desktop That was way too hard to figure out how to do with some obscure DOS code in a little box, I prefer physical buttons!!! Oh and thank God for the old monitors buttons that set size and top to bottom height, etc. mode is now 1280×1024 and for some reason it won’t run at 75 htz like the monitor manual says, it gets all wonky, so 60 htz it is. Why does it have to be so hard? THEN I went to do the final steps with gedit and it is not installed! I guessed I could do the same with mousepad (since I’m on Xubuntu_) and I hope I got that right. OK after typing stuff in for like 2 hours, trying over and over and all kind of errors and stuff, it finally worked. I think Linux is about 20 years behind the times on this one. It only wants to let me set some widescreen thing, 1024X768 OR the old fashioned 800X600 which Windows 95 used. AND I REFUSE to get a new monitor, this one is much better than those flat screen crap ones they now sell with the stupid widescreen, which I never saw the need for! Also it’s native resolution is 1800X1440, which I can’t seem to find in the dropdown. Can’t someone write a damn display thingy that you can click on the numbers you want, picking displays from a list (mine is a Dell UltraScan P1110 – CRT monitor – 21″… which last I checked Window XP had listed, and I used.) Nothing showing up, you cannot select anything from the dropdown. :~$ sudo xrandr –addmode eDP-1 “1600x900_60.00”ĪND it simply does not work. Minor opcode of failed request: 16 (RRCreateMode)Ĭurrent serial number in output stream: 33 Major opcode of failed request: 140 (RANDR) X Error of failed request: BadName (named color or font does not exist) Thern to top it all off I finally get this. No command ‘xrander’ found, did you mean:Ĭommand ‘xrandr’ from package ‘x11-xserver-utils’ (main) THEN you notice, “command not found 1600! WHAT THE HELL? Why would you have to put in ANOTHER command? OK so then the cvt thing. VGA-0 connected 1024×768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm HDMI-0 disconnected (normal left inverted right x axis y axis)ĭVI-0 disconnected (normal left inverted right x axis y axis) I don’t know what else would? I got this…. Then, the thing does not say anything about edp-1 so that does not work. I typed Xrander and it gave an error! Unbelievable. Whye the HELL do you have to do these things in some little DOS box in Linux? Can’t they catch up with other operating systems where you do not have to use this little MS DOS box, and set things in a GUI?Īnd it should be forgiving of your spelling and or typing. Copy the Modeline (words with red underline, see previous picture), and run command to add new mode: sudo xrandr -newmode "1600x900_60.00" 118.25 1600 1696 1856 2112 900 903 908 934 -hsync +vsyncĭoes not work at all. Replace 1600 900 (1600X900 in my case) in the command to your desired screen resolution.ģ. Run command to calculate VESA CVT mode lines by given resolution: cvt 1600 900 ALL I need here is the display device name, in my case, it’s eDP-1.Ģ. It outputs current screen resolution as well as all available solutions. Open terminal via Ctrl+Alt+T or by searching for “Terminal” from dash. To get my screen resolution, I did the following steps:ġ. Though there are options to scale for menu, title bars, and text, I prefer 1600X900 (16:9) which is available in Ubuntu 16.04 LTS by default. On my Ubuntu 17.04 Desktop, the default 1920X1080 (16:9) resolution is kinda high for me. Your preferred screen resolution is not available in the Display settings? Well, here I’m going to show you how to add a custom screen resolution in Ubuntu 17.04 (Work on all current Ubuntu releases). Since Ubuntu 21.04 uses Wayland as default, See another way works on both Xorg and Wayland.
