** Description changed: I've used dual monitor on my machine since Edgy, and used Feisty for a long time since it appeared. After an upgrade approx on 27th of February and reboot, dual screen stopped working (I have LCD + CRT). Moreover, one screen (LCD) was blank till i added HorizSync/VertRefresh (to monitor) or CRT2Hsync/CRT2VRefresh (to device) settings. Same situation is experienced by another person in our company using ubuntu on similar machine. Here are some details from my Xorg log file: (II) Primary Device is: PCI 01:00:0 (II) ATI: Candidate "Device" section "ATI Technologies Inc RV350 AP [Radeon 9600]". (WW) RADEON: No matching Device section for instance (BusID PCI:1:0:1) found (--) Chipset ATI Radeon 9600 AP (AGP) found ---- (II) RADEON(0): MergedFB mode forced on. (==) RADEON(0): Using gamma correction (1.0, 1.0, 1.0) (II) RADEON(0): Validating modes on Primary head --------- (II) RADEON(0): BenQ FP767: Using hsync range of 31.00-83.00 kHz (II) RADEON(0): BenQ FP767: Using vrefresh range of 56.00-76.00 Hz (II) RADEON(0): Clock range: 20.00 to 400.00 MHz --- (II) RADEON(0): Not using default mode "2048x1536" (hsync out of range) (II) RADEON(0): Not using default mode "1024x768" (bad mode clock/interlace/doublescan) (WW) RADEON(0): Mode pool is empty (EE) RADEON(0): No valid modes found (EE) RADEON(0): No valid mode found for CRTC2, disabling MergedFB (II) RADEON(0): Total of 0 CRTC2 modes found for MergedFB------------ (--) RADEON(0): Virtual size is 1280x1024 (pitch 1280) (**) RADEON(0): *Default mode "1280x1024": 135.0 MHz, 80.0 kHz, 75.0 Hz I have tried to switch primary monitor with second in another order, but it affected absolutely nothing. What do I see is the same image on both screens now. + + Setting up a new xorg.conf file with xorg-reconfigure did not help, it + just removed the MergedFB section, adding it back gave nothing. -- dual monitor (mergedfb) stopped working after update in 7.04 approx from 27 february https://launchpad.net/bugs/91586 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
