  1. Hi guys, I downloaded and burned to SDCard the last nightly image Armbian_5.58.180812_Orangepipc_Ubuntu_bionic_next_4.17.14 for OrangePI PC. Added desktop with apps, and it boots to desktop upon login. How to boot straight to desktop, without login and typing startx? I have 4K HDMI display, so must run development images, since stable don't support 4K as I was explained here earlier. The display has 2 main resolutions: 4K and 1080P. But in Armbian Display settings, choosing 4K gives full screen image, and choosing 1080P results in only a portion of display area used by
  2. Here's sudo armbianmonitor -u output. Link to it was present in the 1st post, but somehow auto deleted on its edit:
  3. I'm not asking for out-of-the-box solution, but merely look for a workaround, and besides all smarty non-working drivers there're pretty straightforward "hard-coded" solutions, which can be suggested by more experienced users. Yet NONE is suggested so far. Btw, running LXQT desktop correctly identifies all available resolutions from 4K monitor EDID. So my guess is, uBoot driver tries to run 1st default 4K reso instead of set in extraargs 1080P, and fails to do it, especially without Mali support. Yet hard coding reso works on Ubuntu desktop with legacy kernel. I assume, uBoot graphics driver i
  4. I tried to follow advice from this post, but it didn't work: add line in /boot/armbianEnv.txt : extraargs=drm_kms_helper.edid_firmware=HDMI-A-1:edid/1920x1080.bin video=HDMI-A-1:1920x1080-24@60 I also tried to add similar line in boot.cmd and recompile, and it failed to boot: setenv extraargs "drm_kms_helper.edid_firmware=HDMI-A-1:edid/1920x1080.bin video=HDMI-A-1:1920x1080-24@60" I assume the generic 1920x1080.bin from the distro can be used instead of my monitor edid.bin? The reason is I've a 4K monitor, so not sure if Linux driver will read or e
  5. Tried to boot on another 1080P monitor - and the same OS booted OK. So it looks like uBoot can't read EDID from the 1st monitor. The question is: what are other ways to set monitor resolution apart from reading it from EDID? Can it be directly permanently set in uBoot? Is fw_setenv command supported in Debian Stretch in write mode? Tried fw_printenv, and got "Environment does not start on (erase) block boundary", which results in Read Only access to env from SSH console. Is that the latest uBoot? It seems that error was fixed in Aug 2016, not sure though if its the same uBoot line.
  6. I've a problem with latest Armbian Debian Server stretch (ARMBIAN 5.38 stable Debian GNU/Linux 9 (stretch) 4.14.18-sunxi, Uboot loader 2017.11) on OrangePI One, and OrangePI PC. It boots seemingly OK, but without any output to 1080P HDMI monitor. So I've no video. But Ubuntu Desktop with Legacy kernel boots fine using the same SDCard (and same power supply ). I can SSH to the Debian after boot, here's the boot and diag log. Couldn't wait for senseless SDCard testing to finish, as it works perfect with Armbian Ubuntu Desktop version. Legacy version on 1st boot shown boot progress and defaulted
  7. Can you make a similar tutorial for multiboot with making a separate partition for each distro on your sd card and use it to store the rootfs and other distro files? Also better explain, how to prepare multiboot sdcard for other ARM devices - what would be different as an example for Orange PI, and where to get these different files from?
  8. Great effort! Can you try using BerryBoot ARM Bootloader instead to simplify multiboot for novices?
  9. I was talking about this model, its unregulated, but I don't think it drops to 5V under OPI standalone load. Any simple way to find it out? I'm concerned about PC Monitor impact due to HDMI overvoltage. I assume your application requires passing up to 5A current through OPI. Would such current damage tiny power components of the device? I think, even powering an external 3.5' USB HDD is a bad idea due to high starting current. I found a few interesting power supply options for OPI allowing to use 12V CCTV or laptop adapters: 12V-to-5V 3A adjustable DC-DC Converter 12V-to-5V 3A Double
  10. There're some cheap 5V 3A "LED Strip" power adapters sold on Aliexpress. They measure 6V at idle, but voltage may drop some at load. Can it damage OPI using such an adapter - what components? And if the power port is damaged, would it still be possible to power OPI through the PIN Header as you did? And if 6V is supplied directly via USB and HDMI power pins, can it also damage USB Thumbs and PC Monitor HDMI ports & main board?
  11. Does Armbian currently have Microsoft Wireless Keyboard & Mouse support? If not, can you guys add it? Its not included in loboris's distro images I tried, unless you can point to one where its included.
  12. My best guess is, Steven might have paid loboris ones to prepair a series of working images for OPI line. I do support your notion about paying dues to Armbian team as well, and possibly other distro authors, but success chance may jump a little if you address it directly to Steven Zhao, who seems to be "everything" man in this small company. He didn't seem to reference Armbian on their website.
  13. Can you be more specific what "inherent potential" will be unleashed with 4.x? Also, I was under impression, vanilla 4.5 kernel thus far has minimal device driver support if any. Am I wrong?
  14. @Igor Can you explain your "methodical approach"? What are its priorities?
