On CRT screens, you could adjust your DPI via XFree86 modelines. On LCD screens DPI is fixed so you have to work with that. If the screen supports DDC (it should if it is new), it will tell the X server what the DPI is, so you don't need to set it manually. Running "xdpyinfo" under X will tell you what the resolution is (my current screen happens to report 109x112 DPI = 1600x1200 on a 19" screen). I think GIMP can work with the DPI info reported from the X server.

Console display in portrait mode with unusual dpi resolution
Overview: At business I just got a brand new EIZO 18" LCD display L675 to test its usability for working in portrait mode to show a full A4 page. These test were done on Windows NT4 but I'd really like to know how well Linux would have done. I'm going to describe all the obstacles I encountered on Windows so anybody may knows the corresponding answers for Linux. Maybe there are other problems on Linux? 1. Obstacle While the EIZO L675 is mechanically turnable, it doesn't handle the landscape/portrait mode switch itself. [OFFTOPIC] Are the any other displays capable of this? [OFFTOPIC OFF] The turning software had to be ordered/paid separate (Pivot software). Of course the display should handle it itself, but until this happens a software solution is okay. Is there any software solution for Linux? I've heard there are graphics cards which handles the landscape/portrait mode themselves (i.e. ATI radeon). This is almost as good as if the display handles it, as long as if there are the corresponding drivers available. How about Linux drivers? PS. My good old monochrome portrait monitor from Apple (around 1990) is an fine example. 2. Obstacle The portrait mode software starts working just about before the logon screen is shown. All the BIOS and system messages are shown in landscape mode. This looks funny but is acceptable as long as no user interaction is necessary. So i.e. it needs a rather high concentration to switch to another hardware profile (Windows NT4). From the nature of a software solution I guess this can't be changed neither of Windows NT4 nor Linux. 3. Obstacle The EIZO L675 has a pixel pitch of 0.28x0.28 which is equivalent to about 90dpi. Since Windows (any version) uses a default value on 96dpi, everything is enlarged by about 5%. So even with an 18" display an A4 page can't be normally viewed in Word. Current status from Microsoft "problem is recognized, we are working on it". While there is no solution for Windows (probably until SP1 for XP) what's the status of Linux? PS. My good old monochrome portrait monitor is again an example. While it has 80dpi and Apple defaults to 72dpi on these old monitors (10% decrease) and Macintosh typically there is no useless scrap around, I can view an A4 page. Of course it also shows that even Apple has no solution to the dpi problem. O.
