There's options to swap displays, adjust image quality #Not giving standard mode: 1280x1024, 60Hz ![]() #Not giving standard mode: 1600x1200, 60Hz (if you don't have get-edid then sudo apt install read-edid) There's a limit of 4 settings that you can preset. These are all of the different resolutions supported by the DualHead2go: Anything higher and I get "failed to configure crtc1". On my laptop with Ubuntu 19.04 that has integrated intel graphics, it will only output 2*1360x768 (2720x768) resolution on the VGA port. ![]() The catch is that your computer video card must output a very high VGA resolution, 3840x1080 if you want dual 1920x1080 monitors. If you don't know what a DualHead2Go is, it takes a video signal in and splits it across 2 monitors, effectively giving you an additional monitor out. I got the dualhead2go digital edition which has VGA input and dual DVI outputs. I saw one of these on ebay so I thought I'd give it a spin. Here's another case where it'd be good to have a mode where it wouldn't try to do anything when a new monitor gets detected, just leave things the way they were. It'd be cool to be able to "lock" the audio to a specific output and prefer that setting.Īlso TVs tend to shut themselves off when they have no signal from power saving, and every time I turn the TV back on, the video system detects this and all the screens go black for a moment. I still get audio output from the laptop but I can't control the volume until I set the audio output back to the built-in. The only thing that's irritating now is that when I boot with the dock, ubuntu switches the audio volume controls to the dock. Just remember to have the monitors on the displaylink turned on when you boot. So now I've got 2 monitors on the lenovo displaylink dock, and 2 monitors off the laptop's outputs (HDMI and VGA) plus the laptop's own monitor (the 3 running off the integrated intel graphics).ĥ total monitors works pretty nicely. I gave up on it for awhile, but then realized that if I had the TV on when I started up the computer, everything was fine, no pointer trails and no crashes. But half the time I'd activate the TV, the computer would just freeze. I hooked up my 50" tv to the DVI on the dock with a DVI to HDMI cable. What I noticed was that I'd get weird pointer trails and the display wouldn't update perfectly. Whilst python is heavily supported for the Pi, 'C' is Linux's native language so, if you're comfortable with that, continue but, perhaps, dabble in python in "slow time".I got this Lenovo dual dvi usb 3.0 dock and thought I'd see if I could get it running with my Ubuntu 19.10 laptop.Īfter getting the drivers from displaylink, I gave it a try. etc provided within the CD/DVD image and will have to save your work to either the hard drive or a USB stick. Many distro's have "Live CD/DVD" variants which boot-up without changing anything on your PC harddrive. I happen to use Ubuntu myself (my netbook is "dual-boot" Ubuntu/Windows XP). Re: Other Linux distro's - Given that the Pi's "main distro" "Wheezy Raspbian" is Debian-based, Debian itself, or any other Debian-based distro would probably be a "good start". If you guys could give me some start up tips it would be much appreciated. The project in question would be some sort of video intercom using two pi's and a hdmi TV. ![]() ![]() Second I understand that the advised programming language for the pi is python, I have some C an java knowledge, and would like to know where do I start. I am supposed to do a school project with the RPi, and I am seeking for some advice.įirst of all ,i don't have the pi yet, so I wold like to know if i could start experimenting with other linux distro on my desktop that would be similar.
