Trial of Xen, Xorg, and an Intel graphics controller on wheezy

A few weeks ago, I upgraded one of my Debian box from squeeze to wheezy.
Upgrading task was not so difficult, also I had to manage a trouble concerned with X11.

Then I tried running Xen dom0 kernel upon the Xen hypervisor 4.1. After the installation I booted the hypervisor followed by the dom0 kernel. When a X server launched, the screen was filled with the textile-like tiling patterns. But after several seconds, the normal GDM login console appeared. I did some tasks in the desktop environment, for example, watching a video stream.

During the tasks, I encountered one Xserver's crash and one kernel panic. The thing around Xen and xorg's Intel driver must be getting better. But it seems to be still unstable.

Configuring Network Manager for PPPoE connection

When I'm home, I use fiber-optic line with a dedicated old small router (YAMAHA RT107e) for access to the Internet. But I recently became anxious about the router. If it fails, how can I survive until I get another one? So, I tried to connect my Debian desktop PC to the fiber-optic line without the router. The PC have to talk to the other side of the line with PPPoE but I did not know how. In my PC, the Network Manager manages network configuration. So, I had to configure the Network Manager to utilize the pppoe like : nmcli connection add ifname eth0 connection.type pppoe username USERNAME password PASSWORD

Some adjustment to run some daemon services within LXC container

 I built and am running a mail server, using dovecot for IMAP4 server and Power DNS (pdns) for DNS authoritative server, and memcached for back-end service for some mail filter. I also use LXC for staging environment to test my mail server, but running those services is not straight forward. My understanding is that it is because some security features of systemd using Linux kernel namespace function conflict with the use of namespace in LXC container. So, if you want to run memcached, dovecot, and pdns via systemd within LXC container, you have to disable some security features of systemd by configuration. My additional configuration to systemd is as follows: root@myhost:/# cat /etc/systemd/system/memcached.service.d/99-ns.conf [Service] ProtectSystem = no ProtectHome = no PrivateDevices = no PrivateTmp = no cat /etc/systemd/system/dovecot.service.d/99-ns.conf [Service] ProtectSystem = no PrivateDevices = no PrivateTmp = no root@myhost:/# grep -v '#' /etc/systemd/system/pdns.s...

The final update to Debian 11 has come

Recently, the 11th point release of Debian 11 has been announced, and it will be the last one. For I am still maintaining one Debian 11 machine, I am starting to prepare its upgrade to Debian 12. Because it is a dual boot machine, I must not forget about the change of grub OS probing. Before I ugrade, I have to add  GRUB_DISABLE_OS_PROBER=false to / etc/default/grub,  or I lose grub menu for Windows OS.  Another thing that impacts me is the change of gnome-text-editor. In Debian 11, gnome-text-editor is a kind of alias of gedit controlled under the Debian alternative system with update-alternatives command. On the other hand, a new package gnome-text-editor appears in Debian 12, and it is a different thing from gedit. For I am an uim user, I was confused when I tried to use launch a Japanese input method via uim on gnome-text-editor in Debian 12, for it wouldn't work as in Debian 11. Yes, these two things are important reminder to me.
