[Bug 579292] Re: Switch of user causes display problems
Daniel Bystrov, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications-Accessories-Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful. Thank you for your understanding.

[Bug 579292] Re: Switch of user causes display problems
Hello, I don't have exactly same problem, but I found some problems with xorg when I switch user between openned sessions: PROBLEM: I have session with 1600x1050 and switch to another user's session that was previously set with same 1600x1050 resolution. But when I switch to this session, the screen gets 1280x1024 and for some reason the size of the session is very very wrong (it is bigger than the screen resolution and I can't move or click most of the things so I have to restart all Xorg). WORKAROUND: Fortunately I have found some way to resolv it in a tricky way: Change resolution file name with your resolution file. 1-Install get-edid command: sudo apt-get install read-edid 2-Create a bin file with edid information: sudo get-edid 1600x1050.bin 3-Create a folder to store this file: sudo mkdir /lib/firmware/edid 4-Copy the file: sudo cp 1600x1050.bin 4-Edit grub to edit linux command to load this file in kms: -sudo editor /etc/default/grub -Edit line: RUB_CMDLINE_LINUX_DEFAULT=drm_kms_helper.edid_firmware=edid/1600x1050.bin quiet Change your name.bin file. -sudo update-grub 5-Reboot and test. For some reason it worked for me very well. I have this card and driver: fglrxinfo display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: AMD Radeon HD 6450 OpenGL version string: 4.2.12002 Compatibility Profile Context 9.012 My edid information file is: command: #parse-edid 1600x1050.bin parse-edid: parse-edid version 2.0.0 parse-edid: EDID checksum passed. # EDID version 1 revision 3 Section Monitor # Block type: 2:0 3:fc Identifier 22T41-H-AN VendorName KTC ModelName 22T41-H-AN # Block type: 2:0 3:fc # Block type: 2:0 3:fd HorizSync 15-68 VertRefresh 49-61 # Max dot clock (video bandwidth) 150 MHz # DPMS capabilities: Active off:no Suspend:no Standby:no Mode1280x720 # vfreq 60.000Hz, hfreq 45.000kHz DotClock74.25 HTimings1280 1390 1430 1650 VTimings720 725 730 750 Flags +HSync +VSync EndMode Mode1680x1050 # vfreq 59.883Hz, hfreq 64.674kHz DotClock119.00 HTimings1680 1728 1760 1840 VTimings1050 1053 1059 1080 Flags -HSync +VSync EndMode # Block type: 2:0 3:fc # Block type: 2:0 3:fd EndSection kernel.log: 2139 Oct 2 21:45:06 dans679-computer kernel: [0.00] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-3.8.0-30-generic root=UUID=939b3111-4906- 46ae-9ad7-7faa783d490d ro drm_kms_helper.edid_firmware=edid/1600x1050.bin quiet I was looking for other bug report similar in launchpad, but still looking for the correct one. I would like find a user with same problem I had, because I think this problems affects many things in KMS (Kernel mode switch), not just switching between user session, also games in full screen with different resolution and others things. It is very hard to find the correct way to report this issue, I would like to have some help with some Xorg/Kernel team. I think this could be fixed in some low level, but could be also fixed with this kind of workaround in some easier way for users: For example adding some script that test if edid is detected or not, and asking the user if he liked to let script get the edid info and parse it to the kernel command, then ask if it was working fine and if the user wants to keep these settings. Hope it could help your issue too.
