Hardware Giveaway
by Gordan Bobic 27 Oct '18

27 Oct '18

I've been meaning to get back to some of my ARM hardware, but inbetween all the work commitments it doesn't look like that's feasible before these ARMs will only be good for the landfill. So, if anyone here is interested, here is what is up for grabs, for free: - Toshiba AC-100 x3 (at least one is in it's original box) - Genesi Efika MX Smartbook (in original box) - Compulab SB-A510+CM-A510 (yup, in original box) - Compulab TrimSlice (you guessed it - in original box) All have been used, but are in condition ranging from excellent to mint. If anyone wants any of these for a purpose better than it gathering dust in their cupboard rather than mine, email me off list with a shipping label for posting from mainland UK, and I'll post it to you. Best regards. Gordan

hikey 960?
by Skorpeo Skorpeo 26 Oct '18

26 Oct '18

Has anyone been able to install centos using iso on a Hikey 960? The wiki says "The Hikey from 96boards mostly works, but setup is complex. The installer currently cannot be used as one would traditionally expect." Any guides out there on how to get it to work? I am only able to get it to the initial installation menu but no further, I tried playing with various kernel parameters but to no avail. Any guidance or suggestions would be appreciated!

The kernel are kindly build by Pablo and can be found at: https://armv7.dev.centos.org/repodir/community-kernel-latest/ On a running armhfp device (distro or kernel should not matter); You may mount the sd-card and chroot in to the card to install / update the kernel. Mount the rootfs partition (usually part4) of your sd card and the boot partition (usually part2); mount proc and sys of the "host" too (ie): mount /dev/sdX4 /mnt mount /dev/sdX2 /mount/boot mount --bind /proc /mnt/proc mount --bind /sys /mnt/sys then chroot /mnt You may need to copy the /etc/resolve.conf from your host system to kickstart networking. _OT_ For personal use and on request from others I made a flash-able img file with 4.18.16 installed. It is a bit different from the default userland-generic though: 2 partitions starting @4096 (1) boot (2) rootfs; compressed swap-space in ram.

More notes on Xfce
by Robert Moskowitz 23 Oct '18

23 Oct '18

I am now connected via vnc. I am using the following for my ~/.vnc/xstartup #!/bin/sh unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS # exec /etc/X11/xinit/xinitrc exec /bin/sh /etc/xdg/xfce4/xinitrc xrdb $HOME/.Xresources startxfce4 & No avahi-daemon Oct 23 11:39:29 ct-c7 yum[1950]: Installed: avahi-libs-0.6.31-19.el7.armv7hl Oct 23 11:40:09 ct-c7 yum[1950]: Installed: avahi-glib-0.6.31-19.el7.armv7hl Oct 23 11:51:35 ct-c7 journal: Failed to connect to avahi service: Daemon not running Oct 23 11:51:51 ct-c7 journal: Failed to connect to avahi service: Daemon not running But is it really needed on a server? No cups installed. That would be a separate step, I assume. No auto media mount. I insert a usb drive. I see it in /dev as sdb, but it is not showing on the desktop to mount. Seems I had this when I first installed gnome DE and then installed Xfce DE, and selected Xfce DE. Only ~/Desktop directory created. None of the other directories you tend to see for a user account. I am going to put this drive to the side and work on other stuff for now. Unless someone recommends testing some addition. Meanwhile the install of the Xfce group needs to install Base and "X Windows System" it would seem. thanks

Attempt to install Xfce by hand
by Robert Moskowitz 23 Oct '18

23 Oct '18

You may have seen my posts around on my challenges to build a couple groups to do a group install. That got me to realize, that I probably know which rpms to install and I could 'do it by hand' for now. So first step was: yum install glx-utils initial-setup-gui mesa-dri-drivers plymouth-system-theme spice-vdagent xorg-x11-drivers xorg-x11-server-Xorg xorg-x11-utils xorg-x11-xauth xorg-x11-xinit xvattr tigervnc-server wayland-protocols-devel xorg-x11-drv-keyboard xorg-x11-drv-libinput xorg-x11-drv-mouse xorg-x11-drv-openchrome Where xorg-x11-drv-openchrome was not available, but is flagged optional in the group. This installed 16 packages and 263 dependents. Next the actual Xfce: yum install Thunar xfce-utils xfce4-panel xfce4-session xfce4-settings xfconf xfdesktop xfwm4 gdm leafpad openssh-askpass orage polkit-gnome thunar-archive-plugin thunar-volman tumbler xfce4-appfinder xfce4-icon-theme xfce4-power-manager xfce4-session-engines xfce4-terminal xfwm4-theme-nodoka xfwm4-themes pinentry First this showed: No package xfce-utils available. No package leafpad available. No package thunar-archive-plugin available. No package xfce4-icon-theme available. No package xfwm4-theme-nodoka available. No leafpad is OK, as a check shows that mousepad is available and this is what is in Fedora28. No xfce-utils is not good. It got worst with critical missing dependencies that need to be fixed before I could get this to work: Error: Package: xfce4-power-manager-1.4.1-4.el7.armv7hl (epel) Requires: libxfce4util.so.6 Available: libxfce4util-4.10.1-2.el7.armv7hl (epel) libxfce4util.so.6 Installing: libxfce4util-4.12.1-2.el7.armv7hl (epel) ~libxfce4util.so.7 Error: Package: xfdesktop-4.10.3-1.el7.armv7hl (epel) Requires: libxfce4util.so.6 Available: libxfce4util-4.10.1-2.el7.armv7hl (epel) libxfce4util.so.6 Installing: libxfce4util-4.12.1-2.el7.armv7hl (epel) ~libxfce4util.so.7 Error: Package: xfce4-session-4.10.1-8.el7.armv7hl (epel) Requires: libxfce4util.so.6 Available: libxfce4util-4.10.1-2.el7.armv7hl (epel) libxfce4util.so.6 Installing: libxfce4util-4.12.1-2.el7.armv7hl (epel) ~libxfce4util.so.7 Error: Package: orage-4.10.0-5.el7.armv7hl (epel) Requires: libxfce4util.so.6 Available: libxfce4util-4.10.1-2.el7.armv7hl (epel) libxfce4util.so.6 Installing: libxfce4util-4.12.1-2.el7.armv7hl (epel) ~libxfce4util.so.7 Error: Package: Thunar-1.6.3-2.el7.armv7hl (epel) Requires: libxfce4util.so.6 Available: libxfce4util-4.10.1-2.el7.armv7hl (epel) libxfce4util.so.6 Installing: libxfce4util-4.12.1-2.el7.armv7hl (epel) ~libxfce4util.so.7 Error: Package: xfce4-appfinder-4.10.1-2.el7.armv7hl (epel) Requires: libxfce4util.so.6 Available: libxfce4util-4.10.1-2.el7.armv7hl (epel) libxfce4util.so.6 Installing: libxfce4util-4.12.1-2.el7.armv7hl (epel) ~libxfce4util.so.7 Error: Package: xfce4-session-engines-4.10.1-8.el7.armv7hl (epel) Requires: libxfce4util.so.6 Available: libxfce4util-4.10.1-2.el7.armv7hl (epel) libxfce4util.so.6 Installing: libxfce4util-4.12.1-2.el7.armv7hl (epel) ~libxfce4util.so.7 Error: Package: thunar-volman-0.8.0-6.el7.armv7hl (epel) Requires: libxfce4util.so.6 Available: libxfce4util-4.10.1-2.el7.armv7hl (epel) libxfce4util.so.6 Installing: libxfce4util-4.12.1-2.el7.armv7hl (epel) ~libxfce4util.so.7 You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest I am going to have to put this on the back burner until someone can fix these. I do not have the skill sets to do it. But having Xcfe would be great for an armv7 SOC over Gnome!

Did not find the time to test it with a default img as I'm still in a fight with the odroid HC1. For the latter the good new is: it's not an issue with the kernel but with the initramfs.
