Package: ddccontrol Version: 0.4.2-10 Severity: important Dear Maintainer,
I used to use ddccontrol to adjust the monitor brightness on my EIZO FS2332, which worked fine on my previous system, a Pentium 4 (i386) with nvidia graphics. I now upgraded to an i7 (amd64) with a newer nvidia card, but use the same monitor, and ddccontrol no longer works. Here's what's happening: Probing for the monitor works: ---------------------------------------------------------------------------- # ddccontrol -p ddccontrol version 0.4.2 Copyright 2004-2005 Oleg I.

EDID readings: Plug and Play ID: ENC2263 [VESA standard monitor] Input type: Digital =============================== WARNING =============================== There is no support for your monitor in the database, but ddccontrol is using a basic generic profile. Many controls will not be supported, and some controls may not work as expected. Please update ddccontrol-db, or, if you are already using the latest version, please send the output of the following command to [email protected]: LANG= LC_ALL= ddccontrol -p -c -d Thank you. =============================== WARNING =============================== = VESA standard monitor ---------------------------------------------------------------------------- The "missing entity" is normal, it just means that there is no monitor-specific profile and the generic VESA profile is used. The monitor appears to be accessible via /dev/i2c-5. What is not normal, and what did not happen on my previous system are the "Invalid response" error messages. If you look into the hex dumps, the often expected byte 0x6e does appear in the data, just not at the beginning. It therefore looks like the data might be shifted, or the wrong offsets be used. This is just a guess, but I suppose this could be an effect of the 64-bit architecture? I recompiled ddccontrol from the latest upstream sources, and the problem remains, so its not specifically a Debian package problem. I tried to install the i386 version of the packages (my system is multiarch-enabled) but this failed because ddccontrol:i386 depends on ddccontrol-db:i386, which does not seem to exist (which makes sense since the database should be architecture-independent). Since neither the Debian package nor the upstream project seem to be maintained any longer: Is there an alternative to control monitor settings by computer (because there are no monitor buttons to do that, and the remote is inconvenient)? -- System Information: Debian Release: 7.0 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.2.0-4-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages ddccontrol depends on: ii ddccontrol-db 20061014-4 ii libc6 2.13-37 ii libddccontrol0 0.4.2-10 ii libpci3 1:3.1.9-6 ii libxml2 2.8.0+dfsg1-7 ddccontrol recommends no packages. ddccontrol suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
