From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.2) Gecko/20010726 Netscape6/6.1 Description of problem: I'm using a Toshiba Tecra 8100 laptop with a Savage 3D video card. Through the LCD screen, everything works fine (up to 1024*768). If set the adapter on double display (both monitor and LCD) and put a monitor on the vga adapter it display's fine on the monitor and the LCD (but it's limited to 1024*768 because of the LCD). I can set the adapter on "monitor only" which should make it work as a normal PC-VGA adapter (I want to use 1280*1024). If I launch Xconfigurator, it detects the monitor and the correct sync info. However testing/running X just gives me a blank screen. Operating info of the LG screen returns me an impossible sync frequency. Going through the debug info of X, I see it detecting the LG and reporting a "disabled" TFT/LCD. It even uses a correct sync mode... but it's not what my screen is receiving. I can reproduce this in all resolutions (meaning that even VGA does not work). The resolutions do work in Windows. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Running Xconfigurator 2. Run test or start X 3. Actual Results: Blank screen LG Studioworks 775N (17") monitor reports incoming Sync of 10Khz and 15Hz. Expected Results: X on my screen Additional info: A collegue has the same problem using a Nokia 17" screen with an IBM Thinkpad (ATI Rage Mobility). He's running Mandrake 8.0 and he tried both 4.0.3 ans 3.x drivers (with no success).
When booting in a framebuffer mode (vga=791), the console does display right (in 1024*768). Starting X does not work. So I guess it is not an adapter/driver error, but a problem with X.

Please try the XFree86 4.1.0 update which we released for RHL 7.1 and 7.2 not long ago, and see if that resolves this issue for you.
RedHat 7.2 and Mandrake 8.1 behaves OK now on an IBM thinkpad with ATI Rage Mobility. It also works OK (more or less) on a Toshiba 8100 with a Savage 3D, only quitting X give me a strange console back (but that could be because I didn't upgrade the kernel...) You may consider it resolved Grtz Alain
Comment on attachment 33160 [details] Xfree86.log Comment for attachment Xfree86.log: Xfree86.log when LCD display AND monitor is on. The LCD is the primary display, but the nokia monitor perfectly displays the screen too. Switching the LCD display off and the nokia screen keeps displaying normally (an LG monitor looses picture at this point)
