Setup xorg debian lenny

When I upgraded to Lenny this stopped working. I had to change the resolution each time I changed from external screen to internal screen and back. So, I dove into XRandR. At the same time I also got interested in trying a dual-head setup instead of only an external monitor when one was connected.

I was going to need completely different layouts depending on the external monitor. It took a while before I figured out how to do it, it took a little longer to fight GNOME into submission, but here is how to make it work. I'm not going in to the gory details of XRandR. The Debian wiki has an excellent explanation of XRandR 1. It is possible to set XRandR configurations in the xorg.

When an external monitor is present, set up a dual head configuration. Note that I have placed the screens above each other instead of side-by-side and that they overlap by 26 pixels. If you use any other driver or chipset like an ATI or Intel then you can use a bigger combined size, like x for two 19" monitors side-by-side.

I want these settings to apply when I log in. Either you install a tweaked acpid, or you set hal to remap the keys to keys which can be handled by some software, in our case xbindkeys. The Debian package does not include this file in its acpid package. System Summary lspci Resources Attachments Some configuration files and sample outputs. Wiki Login.

Extra Features. Remember to apply the change to the grub configuration by running update-grub! Domain 0 CPUs There are some useful tweaks of dom0 cpu utilization. By default all CPUs are shared among dom0 and all domU guests. It may broke dom0 responsibility if guests consume too much CPU time. To avoid this, it is possible to grant one or more processor core to dom0 and also pin it to dom0. More information on the available hypervisor command line options can be found in the upstream documentation.

F at the start of the line. To hide a device from Dom0 you will need to pass these boot parameters to Xen when starting. For example if using a Dom0 with M of memory and two devices at F bus, you have pass all of them: At least in Wheezy not tested in Squeeze the xen-pciback module needs to be configured through modprobe.

Configure the xen-pciback module by adding a modprobe include file e. This way, tty1 will show up at the VGA output, and the hvc0 will show up at the serial console.

To keep both Xen and dom0 kernel output on the same tty, just omit the "vga"-related settings from the above setup. The xen-create-image 8 manual page contains information on the available options.

This is fixed in Wheezy. Debian Installer. Unfortunately, this means that to upgrade the kernel used by a domU, one needs to synchronize with the dom0 kernel. Conversely, if the kernel is upgraded inside the domU, i. One way is to upgrade the kernel inside the domU, and propagate by hand the kernel image into a separate directory of dom0, where the configuration for the domU will look for it. A better way is to use PyGrub or PvGrub : dom0 will just hold a version of grub, and use it to load the kernel image from the domU image itself, and thus avoids from having to propagate the kernel upgrade, domU can simply upgrade its kernel and reboot, without even having to destroy the domain.

PvGrub is more secure than PyGrub , because PvGrub runs inside domU itself, thus having the same isolation as the target domU, while PyGrub runs inside dom0 and could an eventual compromise would be very concerning. There are a few catches that one needs to be aware of however: Reference Dom0 Issues The Xen packages will not upgrade themselves. They must be manually removed and the latest Xen packages must be installed from the Debian Squeeze repository through apt.

If you have relied on it, you would have to run ntpd in dom0 and domUs. A Lenny DomU can be upgraded to Squeeze while running on a Lenny Dom0 but it will not be able to be booted until the Dom0 has been upgraded to the Xen
