Debian 9 - 06-Jul-2019 release issue

VCR0VCR0
in AML-S805X-AC

Just a couple of issues, so far.  Wondering if anybody else is experiencing them and whether anybody has figured out a workaround - I'm getting down to seeing what I can do as well and will post a reply if anything comes up.

- I don't seem to have sound.  Maybe it's been a while, but the last time I used Debian on a machine the sound worked out of the box.
- Dragging windows in LXDE is causing a delay.  Full disclosure here, I'm running from a USB flash stick that purportedly runs at USB 2.0 speeds - I'm leaning toward "storage bottleneck" or "usb bus bottleneck".  Any ideas?  I probably will splash the money on an eMMC storage module though...

    I don't have audio via HDMI neither.

    As for dragging windows that tear when moving, by what I understand, the driver (open source) for this Mali 450 GPU is in process. Kernel driver has been approved for kernel 5.2 inclusion. The userspace driver was approved just in April 2019, with some issues yet. This might take some time for open source.

    Later, will try to get proprietary binaries installed to test in Debian.

    Here source on Lima (Open Source) driver being developed for these boards: http://linux-sunxi.org/Mali#Driver

    The same problem to me, installed debian stretch with lxde desktop, and no audio. When I enter on sound preferences, it says that no sound card present.

    Any ideas on adapting any of the existing drivers manually? Or is that a square peg in a round hole b/c of the unique hardware?

    Don't know about that, since im a complete Linux noob but I've found something interesting using this command:
    sudo update-alternatives --install /usr/local/lib/aarch64-linux-gnu/mali mali /opt/libre-computer/model/aml-s805x-ac/mali/lib/aarch64-linux-gnu/gl4es 100
    then:
    sudo update-alternatives --config mali
    which shows the one added earlier for selection, after selection made of the gl4es entry, using 
    glxgears
    works! and window seems GPU acelerated.

    @djismgaming glxgears should already be accelerated on the regular images. The GPU only supports GL ES 2.0 and not regular GL. The GL4ES module emulates commands in GL that are not in GL ES 2.0. You shouldn't need to do your steps since this should already be enabled. What happens when you run glxgears on a stock machine?

    So glxgears uses OpenGL and es2gears uses OpenGL ES 2.0 (subset). If you run glxgears, it should use GL4ES to emulate GL functions not available in the OpenGL ES 2.0 Mali binary.

    Quick question: If I install the stock image and then 'apt update' & 'apt upgrade' am I messing up the stock image?  Is the image designed to function best stock without upgrading any of the packages?

    Please try to, from a default image, run glxgears.

    It does not work without running the command @djismgaming provided.

    hope this helps
    GPU aceleration is not working for windows on xfce debian at this moment
    windows for file manager / firefox /other apps tear a lot when being moved on the desktop
    haven't tried Ubuntu

    just my two cents, is this on a 512M or 1G board. Could be the former does not have enough RAM for this. (I've no idea on whether the images are tested on a 512M board, maybe loverpi can tell).

    Mine is the 1GB version.

    Well, new images today, so I guess this thread will die.  Thanks for all your hard work. Can wait to check it out.

    Here’s a link to the Debian images:

    And here’s a link to the rest of the images listed at the bottom of the page:

    The Debian Buster images are being built now for release as well. grub-install parameters changed between stretch and buster so it caused a lot of confusion.

    I'm running the Debian Buster XFCE image. In the lc_distro_transfer tool (and maybe others?) you are using "lsb_release -cs" to detect whether it is Debian Buster, but lsb_release is not installed by default, resulting in wrong grub-install command and unbootable eMMC. At first I thought a simple "sudo apt install lsb-release" would fix this, but after that I got the following warnings/errors:

    grub-install: warning: Cannot set EFI variable Boot0000.
    grub-install: warning: vars_set_variable: write() failed: Input/output error.
    grub-install: warning: _efi_set_variable_mode: ops->set_variable() failed: No such file or directory.
    grub-install: error: failed to register the EFI boot entry: No such file or directory.

    Can confirm this was fixed in the newest image.
