[Bug 433142] Re: geode driver do not display 1024x600 on (K)UNR Karmic
Hi Frank, The cvt is a linux utility for calculating VESA Coordinated Video Timing modes, given the desired horizontal, vertical resolutions and refresh rate. Gtf is a similar unix utility that basically does the same thing. I have seen other display timing generating utilities including one developed by one of our engineers called lx_gtf.exe, which is distributed with our LX product on our AMD embedded developers website. All these display timing generating utilities seem to give a slightly different horizontal timing, vertical timing or refresh rate, but they are all with in range and for the most part work well. By looking at display panel timing specs you can see that panels a range of tolerable timings, as long as you stay within the specified range the display works good. If you go ousstide their specified range you can see side effects including artifacts on the display screen, the screen shifted to the right to the left, up or down, or part of the display off the screen. So, cvt and gtf are similar utilities that generate display timings.

[Bug 433142] Re: geode driver do not display 1024x600 on (K)UNR Karmic
Hi guys, I just tested 1024x600 resolution on Ubuntu 9.10 (Karmic) with default installation. The geode graphics driver does not have wide screen modes, when it was initially created wide screen modes were not popular, so these modes were not included only the most popular modes at that time were included. Any other modes can be added to the graphics driver and I will work on adding wide screen modes to the geode driver once I return from vacation because I will be out next week. The graphics driver separate panel modes and regular VGA modes. I will add wide screen modes for both panels and VGA modes. So, if there is a particular wide screen mode that you want to make sure I don't miss please specify it to this thread. So, the current work around for the missing modes in the geode graphics driver is to enter the modes in /etc/X11/xorg.conf. Ubuntu 9.10 does not have a xorg.conf so create one as follows: In order to generate xorg.conf you need to switch to one virtual console using the key combination CTRL + ALT + F1. Now execute the following commands: sudo service gdm stop #This command will stop the X. #Now we need to generate the xorg.conf file: sudo Xorg -configure #This has generated the file in ~/xorg.conf.new. #We need to make X use it so we have to put this file inside /etc/X11/ sudo mv ~/xorg.conf.new /etc/X11/xorg.conf #After moving this file to the proper location you can start the X again and verify that it works before you make any changes to it. sudo service gdm start xrandr #shows the available graphics modes and the one with a ' * ' is the currently set mode. By doing the above command you will see that 1024x600 mode is not available. to add it to /etc/X11/xorg.conf do the following: cvt 1024 600 60 Where 1024x600 is the wide screen resolution and 60 is the refresh rate. The modeline result is: Modeline 1024x600_60.00 49.00 1024 1072 1168 1312 600 603 613 624 -hsync +vsync Then open /etc/X11/xorg.conf and add the following line to the bottom of the 'Monitor' section. Notice I change the Modeline resolution name slightly. Modeline 1024x600 49.00 1024 1072 1168 1312 600 603 613 624 -hsync +vsync Then I saved the xorg.conf file and rebooted. Now doing: xrandr # shows that 1024x600 resolution is now available. Now that the new wide screen mode resolution is available you can set it as follows: xrandr -s 1024x600 I only tested this work around on a regular VGA not on a 1024x600 panel. Hope this helps clarify things.

[Bug 377929] Re: Unable to set rotation on AMD Geode LX800
Hi Guys, as I said before rotation is working fine through 'xrandr' and 'xorg.conf' has been deprecated. So, I would like to close this issue, but I am new to this posting and I do not see how to close this issue. I only see the option to report new bug and list open bug, but no option to change status/priority or close issue. Can any one provide me with a little guide on how to close an issue. -- Unable to set rotation on AMD Geode LX800 https://bugs.launchpad.net/bugs/377929 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 377929] Re: Unable to set rotation on AMD Geode LX800
Hi Guys, this is Rigo from Advanced Micro Devices. I looked at this rotation issue using Ubuntu 9.10 which comes with generic kernel 2.6.31-17 and Xserver 1.6.4. I am able to rotate the screen just fine with the default geode driver that comes with this distribution using Xrandr. I used command such as: xrandr -o left xrandr -o right xrandr -o inverted xrandr -o normal Rotation is working just fine with 'xrandr'. One thing I noticed is that 'xorg.conf' has been removed from Ubuntu 9.10, so I could not test the original post of rotation problems with 'Xorg.conf'. Since 'Xorg.conf' will no longer be available in current and future releases of Ubuntu it does not make sense to go to an older version of Ubuntu and try to figure out how to rotate from 'Xorg.conf'. We had already been warned that 'xorg.conf' would be removed in the future releases and instead of trying to fix this issue on one particular Ubuntu version I propose finding out what the original post wanted to accomplish by rotating from 'xorg.conf' and find a work around that would work on all the Ubuntu Linux distributions. For Example if the intention was just to use 'xorg.conf' to rotate the display as the system booted then we can do this from some other script file as the system boots. So, if the person who original posted this issue has not solved this rotation problem, I would like that person to update this issue and let us know what he/she is trying to accomplish so we can suggest a suitable work around to the deprecated 'xorg.conf' way. -- Unable to set rotation on AMD Geode LX800 https://bugs.launchpad.net/bugs/377929 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
