  1. I might try to bridge the external PSU ground attached to the HDMI external adapter ground to a HDMI ground pin wire and see if it helps. I even tried booting without any usb devices, from the same USB PSU divided in two for the HDMI power mod and the Orange PI psu itself sharing the same ground source from the eletric attached psu. Probably this VGA monitor is more sensible than others inputs.. for example I got a TV with vga input and works as it should.
  2. Interesting, thanks. I got two different adapters with different main ICs one seems to be better and in fact before their wires didn't get broken it worked for a while. Now I should resolder all the 20 wires on that and it's quite boring and not even sure I'd get the same result as in the past. I suppose something can be done on the boot config files to boost the data signal to somehow reduce these interferences? Might be a solution to try to shield the adapter with some copper adesive? I've seen some adapters online having that around the whole PCB. Mine didn't have any beside shielded wires.
  3. UPDATE: I tried modding one of the adapters I got powering the 18 pin HDMI line with a 5.0v stable external usb psu and nothing changed so I suppose it's not about the power voltage but something about how the HDMI output is configured. The monitor works perfectly with a VGA video card and I suppose it might have something to do with being an old LCD with old EDID and version. Are there any safe hdmi output options to try?
  4. Hello, I've an Orange Pi H3 board and I should use it on an old vga Acer 15" monitor. Usually with the other SBC and video outputs, I used the usual HDMI to VGA converters that doesn't have an external psu but seems to take the voltage from the 18 pin of the HDMI outputs. With this monitor that is indeed correctly identified by EDID on the adapter and on the Armbian o.s., the screen goes blank and return every few seconds randomly. I measured the PI One H3 pin 18 voltage and it gives out something like 4,6v to 4,8v and I think this might be the problem (?). I remember on the Rpi there was an option to boost the hdmi output and I suppose it increased that. Is there any similar option into the /boot/ files? Or I have to look for an external powered adapter or mod it myself? Hoping that this is the problem, for example on another monitor the signal is stable enough so it might be this monitor to actually need a stronger signal I can't know. Thanks for any suggestions. Bye
  5. I'll try the log command but I don't think it's a problem on the Pi One side but more a problem on the monitors side. Meanwhile I tried to uninstall the LXDE gui version and install LXQT instead to see if it was some installation problem and nothing change. I suppose my DVI TV has an old connection not compatible with modern HDCP modes and needs some tweaks in the settings. The version that were working until I changed the monitor (the hdmi-vga adapters stopped working for real, I tried even a dvd player on it and I suppose they were burned with the Pi hdmi output or they already were used too much) with both Bullseye Debian 5.10.9 sunxi o.s. and now 5.10.4 sunxi stable version. The only modifications I did and was working until the vga adapter died, was to install LXDE instead of XFCE that I think feels heavier than the first. I read somewhere here in the forum there were some lines to configure DVI monitors but I didn't understand which file should be edited. I'm sure if I had a HDMI monitor it would works as usual.
  6. Hello, I've the Pi One H3 version that I always used with a HDMI to VGA adapter that worked ok until lately that stopped working. So I was thinking to connect the board to a TV monitor having DVI connection. I've tried both stable and experimental version of Armbian o.s. and it shows the same problem, basically it boots ok at native resolution (1280x768 60Hz) until it starts the desktop GUI and it goes to "no signal". If I return to the text console mode the monitor feel the signal again and at the same native panel resolution. I've tried both HDMI to DVI adapter at the monitor side and also an HDMI to DVI adapter and using a DVI cable on the board side and nothing change. I tried forcing the enviroment variable to set the native resolution but it already booted at the correct one. I've read about problems with DVI adapters and maybe some line to add for compatibility problems or whatever. Any hints? Are there any file to edit to add these without using scripts or external tools? The monitor works with a Raspberry Pi so I suppose is just something to set correctly to make it work. Thanks!
  7. I compiled and installed already both Box86 and Wine but I still didn't understand how it actually works to launch a .exe installer/executable with both software running in which order. Should the launch of the apps be Box86 -> Wine -> x86 Win exe file? Both the software did compile without any specific config but even without errors.. now I only need to understand how they actually works.. I had memories of running Wine on x86 linux and it was great obviously on x86 for retrogaming but here things are a bit more difficult.
  8. Hello, Thanks to the help here I got to install a latest armbian mainline version with the Lima OpenGL 2.1 support functional that might have not helped the desktop but is still nice to see the o.s. using any part of this system on a chip. To make some test after glxinfo e glxgears I tried the yquake2 engine with the demo old game and it works. I was expecting considering how old the game is to work faster even if it's accelerated for sure and expecting better quality results (bilinear filtering is not the best and sometimes objects disappear and reappear depending on the scene but it's a good test anyway). I heard lately that has been released a free software for the rpi4 and other arm boards to run x86 programs and even Wine with it. I understand that its SoC and ram are far faster than the H3 ones but I was wondering if anyone tested if the pi One could run old x86 games (like late 90's Directx6 ones for example) on these board or tried to. Thanks
  9. Update: as suggested that was the problem, I've installed the latest Bullseye distribution with latest kernel and Lima opengl drivers seems to be seen everywhere while glxinfo gives me 0MB of video memory, do I have to set it up somewhere? Anywhere I'll do some test but it's already a good point even if I had to install xfce desktop cause I didn't know if lxde would have worked the same way with DRI acceleration and Opengl. Maybe there're not many differences but I felt lxde to be a bit faster. Regarding VDPAU I get this error with vdpauinfo: failed to open VDPAU backend libvdpau_sun4i-drm.so: cannot open shared object file: No such file or directory Do I have to compile it?
  10. Thanks for the explanation. I imagine also that the main limit will still be the ram that already feels like should be at least double the actual one for such modern kernel/os/apps, but I thought I liked the idea to see the GPU and the video engine working as supposed to be. Even in some older SoC for others well known SBC that used the old ARM11 armv6 cpus, it was impressive to see the omx video engine decoding 1080p test codec on such old architecture with few impact on the cpu usage. I suppose that given the specs of this H3 chip things might be even better with the right drivers/modules.
  11. Thanks, I thought Buster was one of the latest still updated versions so I hope/hoped to make these work even in this distribution. I checked with glxinfo and it clearly says it's using the software opengl renderer not any specific driver. Should I reinstall all the o.s. or I can upgrade this one? And aren't the modules usually upgraded along with the kernel installation of the new mainline one?
  12. Hello, I got a Orange Pi One H3 based board with the usual 512MB DDR3 ram and never used it much but lately I'm trying to use it as an everyday home computer, so I'm trying to push the hardware as much as possible to benefit from any features. I actually have installed latest armbian v5.9.x kernel o.s. with Buster distribution and with some zram usage it's quite acceptable on the speed side. I had to add an heatsink on the SoC cause after latest mainline kernel temperature it seems to get close easier to 80°C degrees and even if I suppose it might work even at these temps, I think it was better to lower it down a bit (probably 5° to 10°C degrees). No overclocking and max 1.0Ghz. I'd like to ask if with these kernel version is still possible to install OpenGL drivers and video hw decoding drivers to use some sw like Vlc or Smplayer to see how well it works with media file and games. On the kernel modules I can already see there's a sunxi-cedrus module, v4l2_mem2mem, videobuf2_dma_config/memops/v4l2 modules, Lima DRM and GPU scheduler modules too. Any guide to follow in case it's possible to install both OGL and VDPAU/whatever hw acceleration? Thanks
  13. Hello, I'm a new Armbian user of my first OrangePI One H3 board after much time spent on rpi boards. I was curious to see how these boards run and I bought one. I'm using a fast 32GB A2 microsd, an external 4 USB externally powered hub, an HDMI to VGA converter with audio out. I was deciding at first which o.s. to use cause I've seen there're also Ubuntu and Debian official 5.x kernel based images on their page but I tried this at first. I've installed usual applications browsers office apps mail etc, and now I'd like to make some questions to better understand some things: 1) I know being on the armbian forum I'd expect everyone to prefer this o.s. but I'd like to know which are the differences with the official Ubuntu/Debian images in terms of proper hardware usage (drivers, acceleration, etc..) and generally if you've tried both and your advices on them. 2) Obviously with 512MB od DDR3 I wasn't expecting a full web browser experience cause immediately ram is filled up and begin to swap on disk. I've tried to increase zram to around 400MB setting at 90% but still seems not enough. Are there any possibility to increase it more like 1GB but still preferring to use the internal faster ram as primary choice? 3) I understand there's no Opengl acceleration and usually I'd not need it but still I'd like to understand which is the actual accelerations implemented that use some hardware maybe for 2D at least. I've tried followed the guide to compile everything for the video acceleration at least but at the end in the xorg.log I got some errors with the FB calls changing the acceleration compared to the original auto configurated one and got higher cpu usage then before in mpv compared to the original configuration. Also I've seen for example in some browser it calls the llmvpipe software renderer others seems not to use any acceleration at all. Which is the actual best 2D and eventually 3D configuration for the latest armbian 5.4.26-sunxi kernel based enviroment on the Allwinner H3? 4) I'm using a PSP power supply with 1500mah, is it ok for the connector size and mah supply until I wait for the usb cable to arrive? 5) Using the externally powered USB HUB if I switch off the board and I remove the power supply connector from the pi one, the board still receive some current from the usb powered hub until I disconnect that too. Is it dangerous for the board itself this redundance of power? Thanks I'll update with more questions. Bye
