Tigervnc black screen1/28/2024 ![]() This is only the case when a physical display is connected. With both DietPI and Debian stretch the glxgears is smooth and fast but with Ubuntu, is laggy and slow.Īt this point, I will just set aside my rock64 and wait for an emmc version of DietPI that for what I saw and tested, if the fastest distro out there for the rock64. to TigerVNC User Discussion/Support When we are trying to connect with vncviewer to a remove server running Xvnc, we get a black screen. At this point I really think is related to the video driver.įor some reason, the video driver under Ubuntu are not activated and/or working properly. Please do post back if you figure out what the exact issue was. It could be that '-fno-stack-protector' option, I'm not sure but this is how I got it working. configure -build=aarch64-unknown-linux-gnu -prefix=/usr/local CFLAGS='-g -O2 -fno-stack-protector -Wall' Sudo apt-get install -y libxtst-dev libssl-dev libjpeg-dev zlib1g-dev (01-19-2018, 06:58 AM)dontpostalot Wrote: Here are my notes on the x11vnc compile: I am running tigervnc-server on CentOS 6. Also, when I set the Marco GPU compositor, it works. After it the screen is locked there seems no way to login again through vnc, the screen keeps black. ![]() I have much more frame/sec with glxgears especially in full screen mode. Also, the GPU acceleration works much better. I just tried out DietPi and X11vnc works wonderfully. Is not Ubuntu suppose to install the driver for the ARM Mali-450MP2 automatically? Of course, I may be wrong.Īt this point I have a question. That's why, I do not think this is a coincidence. In addition to this, I also noticed that if I select any Marco with GPU compositor, my desktop turn all black and only the mouse cursor is visible (same behavior as x11vnc). When in TigerVNC you can use the F8 key to change settings. This is the only difference between my Odroid XU4 and the Rock64 (I have used the same configuration files).Īnyhow, I have tested the GPU acceleration on my Rock64 with and I get 1 fps with 1 fish. I was able to ctr-alt-del and get the task manager to exit out of TigerVNC. I think the problem is related to the GPU video driver that for what I saw, they are not working and/or not installed by default by Ubuntu. After spending more than 4 hours looking for a possible solution, I might know what could cause this issue.
