Package: xserver-xorg-core Version: 1:1.0.2-8 Severity: normal After a recent apt-get upgrade, I have noticed severe problems with the screen becoming garbled on my Thinkpad X40. This may happen only after an APM resume; I'm not sure. Strangely, the problem can sometimes be cured by repeatedly switching back and forth between internal and external display using Fn-F7.
I'm not sure how to describe the symptoms; the best I can do is that a thin strip of scan lines---maybe three pixels high or so---becomes replicated across a large fraction of the window, and the rest of the window goes blank. It's almost as if the scan lines are scrambled somehow. The effect is confined to a single window and doesn't affect other windows on the same screen. The two applications where the problem shows up consistently are xterm and emacs: * When xterm scrolls, the part of the window that is newly painted becomes scrambles. The problem can be mitigated by setting 'Jump Scrolling' off in the xterm's ctrl-middle-click window. * When emacs scrolls and repaints, the window can become scrambled, and typing ctrl-l to refresh the window scrambles the window completely. Most interestingly, if I use my window manager to change virtual panels on the desktop (I'm using fvwm), switching away from and back to the offending application completely cures the screen. Likewise, forcing a scrambled window to the bottom and then to the top fixes the problem. Finally, dragging a small window over a bad window causes the obscured regions to be repaired when they are uncovered again. All these symptoms lead me to conjecture that when the app is asked to paint the screen, it works fine, but some kinds of scrolling requests cause the strangeness. That's why I'm reporting the bug against /usr/bin/Xorg (my best guess) as opposed to something else. I know this one is going to be hard to reproduce; please let me know if I can provide other information. (And I'm not sure I know how to downgrade to a previous version, but if you would like me to try that and check for results, let me know that too.) -- System Information: Debian Release: testing/unstable APT prefers testing APT policy: (500, 'testing'), (500, 'stable'), (50, 'unstable') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.15-1-686 Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) Versions of packages xserver-xorg-core depends on: ii libc6 2.3.6-13 GNU C Library: Shared libraries ii libfontenc1 1:1.0.1-6 X11 font encoding library ii libgcc1 1:4.1.0-4 GCC support library ii libxau6 1:1.0.0-3 X11 authorisation library ii libxdmcp6 1:1.0.0-4 X11 Display Manager Control Protoc ii libxfont1 1:1.0.0-4 X11 font rasterisation library ii x11-common 1:7.0.22 X Window System (X.Org) infrastruc ii xserver-xorg-input-al 1:7.0.22 the X.Org X server -- input driver ii xserver-xorg-input-ev 1:1.0.0.5-2 X.Org X server -- evdev input driv ii xserver-xorg-input-kb 1:1.0.1.3-2 X.Org X server -- keyboard input d ii xserver-xorg-input-mo 1:1.0.4-3 X.Org X server -- mouse input driv ii xserver-xorg-video-al 1:7.0.22 the X.Org X server -- output drive ii xserver-xorg-video-ap 1:1.0.1.5-2 X.Org X server -- APM display driv ii xserver-xorg-video-ar 1:0.5.0.5-2 X.Org X server -- ark display driv ii xserver-xorg-video-at 1:6.5.8.0-1 X.Org X server -- ATI display driv ii xserver-xorg-video-ch 1:1.0.1.3-3 X.Org X server -- Chips display dr ii xserver-xorg-video-ci 1:1.0.0.5-2 X.Org X server -- Cirrus display d ii xserver-xorg-video-cy 1:1.0.0.5-2 X.Org X server -- Cyrix display dr ii xserver-xorg-video-du 1:0.1.0.5-2 X.Org X server -- dummy display dr ii xserver-xorg-video-fb 1:0.1.0.5-2 X.Org X server -- fbdev display dr ii xserver-xorg-video-gl 1:1.0.1.3-3 X.Org X server -- Glint display dr ii xserver-xorg-video-i1 1:1.1.0.5-2 X.Org X server -- i128 display dri ii xserver-xorg-video-i7 1:1.0.0.5-2 X.Org X server -- i740 display dri ii xserver-xorg-video-i8 1:1.5.1.0-2 X.Org X server -- Intel i8xx, i9xx ii xserver-xorg-video-im 1:1.0.0.5-2 X.Org X server -- IMSTT display dr ii xserver-xorg-video-mg 1:1.2.1.3.dfsg.1-2 X.Org X server -- MGA display driv ii xserver-xorg-video-ne 1:1.0.0.5-2 X.Org X server -- Neomagic display ii xserver-xorg-video-ne 1:0.1.4.1-3 X.Org X server -- Newport display ii xserver-xorg-video-ns 1:2.7.6.5-2 X.Org X server -- NSC display driv ii xserver-xorg-video-nv 1:1.0.1.5-2 X.Org X server -- NV display drive ii xserver-xorg-video-re 1:4.0.1.3.dfsg.1-2 X.Org X server -- Rendition displa ii xserver-xorg-video-s3 1:1.8.6.5-2 X.Org X server -- S3 ViRGE display ii xserver-xorg-video-sa 1:2.0.2.3-4 X.Org X server -- Savage display d ii xserver-xorg-video-si 1:1.3.1.5-3 X.Org X server -- SiliconMotion di ii xserver-xorg-video-si 1:0.8.1.3-2 X.Org X server -- SiS display driv ii xserver-xorg-video-si 1:0.7.1.3-2 X.Org X server -- SiS USB display ii xserver-xorg-video-td 1:1.1.1.3-3 X.Org X server -- tdfx display dri ii xserver-xorg-video-tg 1:1.0.0.5-3 X.Org X server -- TGA display driv ii xserver-xorg-video-tr 1:1.0.1.2-2 X.Org X server -- Trident display ii xserver-xorg-video-ts 1:1.0.0.5-2 X.Org X server -- Tseng display dr ii xserver-xorg-video-v4 0.0.1.5-1 X.Org X server -- Video 4 Linux di ii xserver-xorg-video-ve 1:1.0.1.3-2 X.Org X server -- VESA display dri ii xserver-xorg-video-vg 1:4.0.0.5-2 X.Org X server -- VGA display driv ii xserver-xorg-video-vi 1:0.1.33.2-3 X.Org X server -- VIA display driv ii xserver-xorg-video-vm 1:10.11.1.3-2 X.Org X server -- VMware display d ii xserver-xorg-video-vo 1:1.0.0.5-2 X.Org X server -- Voodoo display d ii zlib1g 1:1.2.3-11 compression library - runtime Versions of packages xserver-xorg-core recommends: pn xkeyboard-config <none> (no description available) -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
