@elleto
Thanks for your report.

In the first place there seem to be an issue with the DNS settings, since the URLs are definitely available, e.g.: https://raw.githubusercontent.com/Fourdee/DietPi/master/.conf/desktop/wallpapers/dietpi-logo_1080p.png

• Please verify that also ping raw.githubusercontent.com fails with name resolution.
• How did you setup your network, DHCP or static IP?
• If DHCP, please verify that you have a valid entry in cat /etc/resolv.conf, which should be in most cases the IP of your router, in some cases an external DNS server. You can check by web searching the IP. Also verify in this case that this DNS server IP can be accessed via ping.
  
  
  
  • If somehow the DHCP server does not serve a valid DNS entry, please try to apply a static IP (also setting your DHCP server/router to assign always this same IP to the XU4.
  
  
• If you chose static IP, please verify the static DNS entry in diepti-config > Network Options: Adapters > Ethernet|Wifi is set correctly to either your router IP or a valid external one. 8.8.8.8 (Google DNS) should always work in case.

Actually this name resolution error should have already a failure when downloading the xorg.conf: https://raw.githubusercontent.com/Fourdee/DietPi/dev/.conf/dps_6/xorg_xu4.conf

• This would then be a good reason for desktop to fail.
• On the other hand, dietpi-software should have cancelled already earlier then 🤔. Perhaps it is also just a temporary issue with the DNS server.

However please check the above and, if ping raw.githubusercontent.com succeeds, try to reinstall the desktop: dietpi-software reinstall 24

ok will try it and get back to you
thanks

i checked the ping and have no issue reaching out to the githubuser content, DNS server and google.
after which i tried to reinstall MATE with the command given.

still having the same issue of a list of stuff is not downloaded.

[elleto]

i managed to bypass the download issues by using a different wan network. but i still end up with the xorg error.

and if i use dietpi-autostart i get this

@elleto
Okay, according to the error message, it is not related to the previous issue #2130
Due to lack of XU4 I can't test here, hope @Fourdee finds some time soon.

About the download issues:
Do you have an idea about the reason for name resolution errors with your prior WAN? If is simply has an outdated or unreliable DNS table, then similar things should happen to all other devices. Since GitHub (+sub domains) should be really well known I don't know about any other reason why it throws errors there.

@elleto
Coming back after a long time, sorry for that.

Your issue, if still present, might be related to: https://github.com/MichaIng/DietPi/issues/2584

Something about the mali/mesa drivers for Odroid (XU4) has been changed and seems to be incompatible with out xorg.conf. If is possible to reset it by let it being overwritten with the one from the xf86-video-armsoc-odroid package. Try:

apt-get dist-upgrade # Assure everything is up-to-date
apt-get install --reinstall xf86-video-armsoc-odroid

If this also solves the desktop start issue, I believe we should skip placing custom xorg.conf files and instead rely on the ones now created/updated by the above package.

Requires testing to verify.

Testing passed, Mate running fine 🈯️

Resolved and patched in v6.22.
