Re: X11VNC headless resolution

I have hdmi_force_hotplug commented in in that file, as is hdmi_group and hdmi_mode. If I set that as PeterT explains to hdmi_force_hotplug=1 hdmi_group=2 hdmi_mode=16 ([email protected]) Does the Pi still find a monitor which may be connected at one point? Does it set the screen resolution accordingly?...

Re: Ubuntu no /dev/gpiomem - how to create?

Did you solve your problem? I have the same, the gpiomem module loads, but /dev/gpiomem device is not created. I eventually ended up using a 64bit compiled version of the raspbian kernel by sakaki ( https://github.com/sakaki-/bcmrpi-kernel ), I load this kernel with the raspberry pi build in boot l...

Re: [SOLVED] Unable to USB boot 64bit OS - Grub only has (memdisk)

PS: This download/install/cleanup process can easily be packaged, of course, as I have done here for this kernel autobuild on Gentoo, and as ava1ar has done (using these tarballs as upstream) here for Arch (AUR). How would you go around doing this packaging stuff? I want an automated way to update ...

Thank you very much. After replacing kernel8.img with the files provided, I was able to boot. It even creates the /dev/gpiomem device that I was missing before and couldn't get to load for the life of me. Using this udev rule in /etc/udev/rules.d/60-gpiomem.rules I was able to set the group and perm...

Re: Unable to USB boot 64bit OS - Grub only has (memdisk)

Thank you very much for your answer. The issue here is unfortunately that the bootloader (uboot and grub) are in partition 1, and ubuntu, is on partition 3 (ext4), along with it's /boot/ directory, which has the kernel and initramfs and nothing much else that's active and working. I can install grub...

Re: Unable to USB boot 64bit OS - Grub only has (memdisk)

it doesn't seem to be of much benefit on a Raspberry Pi over its own bootloader. I don't understand the Pi's own bootloader. I'd use it if I knew how. also it's an 64bit kernel, which is located at /dev/sda3/boot/vmlinuz or (hd?,msdos3)/boot/vmlinuz/ I cloned the image from the sd card to the m2 sa...

Getting a bit desperate here. I'm gonna cross compile this kernel:

and hope for the best.

It does not make sense.

Re: Ubuntu no GPIO device

Have a look at the raspberrypi-sys-mods package? If something doesn't work, a good place to look is the Ubuntu flavour maker source code. That often shows the extra packages that are needed. That package doesn't seem to be in the default repository. I did find it here though: https://github.com/RPi...

Ubuntu no /dev/gpiomem - how to create?

The way I understand it is that on raspbian there is a device /dev/gpiomem with 0660 and owner root:gpio, set by an udev rule similar to this: (I have no clue about udev rules, I copied that from the rpi-gpio-common package) SUBSYSTEM=="bcm2835-gpiomem", KERNEL=="gpiomem", GROUP="dialout", MODE="066...

that's odd.
It worked just fine for me on Ubuntu 18.04 LTS on oracle virtual box. after apt-getting build-essentials.
