10.0 external monitor at different resolution
Hi, I want to be able to run (intermittantly) an external monitor at a much higher resolution than the display on my laptop. I know I could probably do this by having two different X config files and manually switch between them. Is there an easier way ? eg issue command at CLI, switch off laptop monitor (output is then automatically piped to external monitor : works fine but only at native (low) LCD resolution). On the Novell site there is mention on enabling output to another monitor (which I can already do) but not at a differing resolution. There is also a comment that this does not work in 10.0. Many TIA, F

I don't have any laptops. However, I do use multiple resolutions on one display at one time on 10.0. I do it with different logins. I have multiple xorg.conf versions with various resolution and DPI settings. So, user2 has in ~/.profile & ~/.bashrc 'export XORGCONFIG=xorg.user2', user3 has in ~/.profile & ~/.bashrc 'export XORGCONFIG=xorg.user3', etc. I've found no way to have the DM recognize $XORGCONFIG, so I only let user1 use the default xorg.conf with the DM, and then I log the other users in on the consoles and then 'startx -- :1', 'startx -- :2', etc. HTH -- "Wisdom is supreme; therefore get wisdom.

This is not a standard use case, thus there is no automatism. You can configure your Xserver to use clone mode, with a higher resolution, but a lower resolution configured as default. When you attach your external monitor, you can switch to the higher resolution (xrandr / your favorite monitor resolution applet). You have to make sure the external output is activated, and the monitor DDC is *not* used (because there often is no external monitor attached on startup). If you have an intel graphics chip, you have to patch the bios (/etc/sysconfig/videobios) for both resolutions, if both are non-standard or not included in the bios. Read: it's possible, but it's truly advanced stuff.

This means you can have only one of this resolutions at the same time, right? Is there a solution in the meantime to use 2 different resolutions at the same time wiht identical content, as in the classical laptop with beamer scenario? Last time I checked I found no solution for this, which drives both displays in their native resolution, always one had to scale, which looks ugly on LCDs. I'm sure at least some laptop graphic chips support this, as under Windows this is possible to do it on my chief's laptop. Ciao Siegbert

Only if you're doing a Xinerama type display (I'm including Merged Framebuffer here), having two independent displays, or by having a virtual resolution with panning on the smaller display. It wouldn't make sense otherwise. Configuration is similar, though a bit more complex.
this, which drives both displays in their native resolution, always one had to scale, which looks ugly on LCDs. I'm sure at least some laptop graphic chips support this, as under Windows this is possible to do it on my chief's laptop.
At least intel chips have handcrafted drivers on windows. A luxury we don't have. So with intel you have much less options. Again, this is non-standard configuration, and complicated to abstract, that's why sax2 does not support this.
