Red Hat Bugzilla – Bug 597805
ATI Radeon 3650 and external monitors
Last modified: 2018-04-11 13:52:16 EDT
I'm using a T500 Lenovo laptop including an ATI HD 3650 graphics card. Until upgrading to the new Fedora 13 version it was possible to plug an external monitor. By now, the system does not recognize any external monitors - not via docking station and not when connected directly by display port.
Version-Release number of selected component (if applicable):
X.Org X Server 1.8.0
Release Date: 2010-04-02
X Protocol Version 11, Revision 0
Build Operating System: x86-02 2.6.18-164.15.1.el5
Current Operating System: Linux 18.104.22.168-95.fc13.x86_64 #1 SMP Thu May 13 05:16:23 UTC 2010 x86_64
external monitor is not recognized.
external monitors are displayed within the monitor preferences dialog.
Another monitor is recognized, yet max resolution is 1024x768 instead of 1680x1050.

thank you for answering. I doublechecked that "bug" twice and came to know, that the two monitors I tested with both do not work any more. On a working monitor, everything works fine.
Thus, thank you very much and sorry for the inconvenience.
