Jack83 Posted May 13, 2016 Posted May 13, 2016 Hi everyone, I bought an Orange Pi oneas a cheap replacement for the unobtainable Raspberry Pi Zero for a little Emulation project. Right now I don't know if it was the right decision:) I wanted to add a waveshare 3.5" display to the orange pi, but I don't even get there. I downloaded the armbian distribution v5.10 legacy Jessy desktop. After the start of the desktop, icons, the taskbar and open windows disappear at random, icons return but the taskbar does not, The desktop is unusable. A similar problem happens in the console, I don't see the cursor where I'm typing. On the command line, thats acceptable but using an editor like nano I have no idea where I am. I suspect a thermal problem as the pi gets hot as hell! Ideling in the console, I get 70°+ with a heatsink. Dmesg is filled with errors setting the cpu freq. I thought the fix for that kind of problem was included into armbian? I hope my orange pi is not defective, it took forever to ship from china Thanks for your help!

RagnerBG Posted May 13, 2016 Posted May 13, 2016 I downloaded the armbian distribution v5.10 legacy Jessy desktop. I don't know whats the problem with Armbian desktop in latest images, but about disappearing icons and stuff i recommend you uninstall build-in XFCE and install it again, or try other lite desktop. The easiest and complete way, i think, is through tasksel. Install it, if it's not already there and execute it with sudo (sudo tasksel). Then deselect "Desktop Environment" and "XFCE" -> ok and this have to make full uninstall, then reboot. After this you can add it again, or some other like LXDE which i prefer, using tasksel, or aptitude, or apt-get. tasksel will fill you with more stuff you probably don't need, so it's better to use apt-get and manually add packages you want. If you still have a problems after this, you probably need to install mali driver and fbturbo again, as i don't have such problems in LXDE. About non seen cursor in console it's a common issue i don't have a clue. I can only speculate maybe it has something with missing G2D acceleration in H3 architecture, which provide 2D acceleration like hardware cursor. But even if you fought through this, i think it's not gonna be much easy with this GPIO display. I have not tried this yet, but you may drop an eye on this topic - Tiny 3$ lcd on orange pi.
Jack83 Posted May 14, 2016 Author Posted May 14, 2016 Thanks for the replies! Fixed the thermal problems according to the thread and it works. I was under the impression that the fix was already included. I could fix my cursor problem with the help of this https://archlinuxarm.org/forum/viewtopic.php?f=63&t=8389 The Problem with disappearing icons unfortunately remains. I uninstalled the desktop environment purging using apt-get and reinstalled without change. I compiled the mali driver and installed fbturbo from source and the error still occurs. In the next step I tried to start X manually and tried a manual start of the window manager with "DISPLAY=:0 mate-session". Moving the mouse over the icons I get the following error from mate and the icons disappear : caja: ../../../../src/cairo-gstate.c:1279: _cairo_gstate_fill: Assertion `gstate->opacity == 1.0' failed. Google gave no usable results. I still hope its not defective. As for the display, one step at a time
tkaiser Posted May 15, 2016 Posted May 15, 2016 I compiled the mali driver and installed fbturbo from source Why? Why do people think stuff like this would be 'necessary' with an Armbian desktop image? Did you already checked your SD card for errors? See user documentation for the appropriate tools. Starting with Armbian 5.10 you could also start armbianmonitor -c $HOME to test the card for errors (might take some time if you've a slow card so better run this overnight)
Jack83 Posted May 15, 2016 Author Posted May 15, 2016 Why? Why do people think stuff like this would be 'necessary' with an Armbian desktop image? Maybe because it was suggested or maybe because fbturbo was not running. You are right that I don't expect it to be necessary, but if I get problems I try to solve them. I tried several cards with several images from the orange pi homepage (Debian based, Fedora...) and they all suffer from the same problem. So it seems to be a problem with my Orange Pi. I will try to contact the seller and get a replacement.
tkaiser Posted May 15, 2016 Posted May 15, 2016 but if I get problems I try to solve them. Well, I wouldn't call this problem solving but YMMV. You wasted already so much time in trial&error mode, why don't you give armbianmonitor a try?
Jack83 Posted May 15, 2016 Author Posted May 15, 2016 I'm happy for every input you can give me, but as no one has seen a similar problem, trial&error is all that is left from my point of view. I gave armbianmonitor a try and it was faster than I suspected. 21mb/s read, 8mb/s write speed. On my 32gb card it found no errors, all sectors are ok and Health summary: OK
