Hello, For all my Debian's computers, I usualy configure my consoles with the vga=791 (VESA framebuffer console @ 1024x768x64k). It works very well. Now, I'm working on a digital kiosk project with Linux embeded, but my screens are all mounted verticaly (it's a kind of photomaton with only a portrait mode). For the support of our solution, it's very hard to type console commands having the neck broken during hours. :( Is there a 768x1024 (for a screen mounted verticaly!) framebuffer mode? And, more generaly, is there a way to set all modes in a vertical way? What can be the consequences with X? Thanks, -- Jean-Martial. |

Boot options The framebuffer console has several, largely unknown, boot options that can change its behavior. <snip> 4. fbcon=rotate:<n> This option changes the orientation angle of the console display. The value 'n' accepts the following: 0 - normal orientation (0 degree) 1 - clockwise orientation (90 degrees) 2 - upside down orientation (180 degrees) 3 - counterclockwise orientation (270 degrees) The angle can be changed anytime afterwards by 'echoing' the same numbers to any one of the 2 attributes found in /sys/class/graphics/fbcon rotate - rotate the display of the active console rotate_all - rotate the display of all consoles Console rotation will only become available if Console Rotation Support is compiled in your kernel. NOTE: This is purely console rotation. Any other applications that use the framebuffer will remain at their 'normal'orientation. Actually, the underlying fb driver is totally ignorant of console rotation. > What can be the consequences with X? According to http://ubuntuforums.org/showthread.php?t=360596 you can add; Option "Rotate" "CCW" to the device section in xorg.conf. Also, this *might* help http://linux.derkeiler.com/Mailing-Lists/Ubuntu/2007-10/msg02746.html Google is your friend. http://www.google.com.au/search?q=linux+fb+rotation http://www.google.com.au/search?q=linux+screen+rotation James. |
