Red Hat Bugzilla – Bug 480620
Automatic detection of external monitor fails on lenovo Y410
Last modified: 2018-04-11 12:19:07 EDT
Description of problem:
The first time i connected an external monitor to the vga port of my laptop (a lenovo Y410), and restart X, the system failed to detect the external monitor (ie: the motnitor, still showed the "no signal" status message).
After this, I tried using system-config-display to configure dual head, but here the "Second Video Card" drop down was empty (so, i presume that is the problem, for some reason, the hardware is not visible to the driver). When I
tried to save the configuration, inspite of the empty "Second Video Card" option, i naturally got a traceback:
[steve@laptop ~]$ system-config-display
Traceback (most recent call last):
File "/usr/share/system-config-display/xConfigDialog.py", line 212, in ok
if card.getDescription() == self.secondVideocardOptionMenu.get_menu().get_active().get_data("NAME"):
AttributeError: 'NoneType' object has no attribute 'get_data'
So, i unchecked the dual display option and restarted X. Now, the external monitor did get the signal but it now runs as a 'clone' (ie: the screens on the primary LCD and the external monitor as the same). Also, the external monitor
resolution is stuck at that of the primary display.
A sosreport is attached. Please let me know if you need anything else.

Steps to Reproduce:
1. Install F10 with latest updates on lenovo Y410 laptop
2. Connect an external monitor
3. Try to configure displays to have individual desktops
The external monitor display is a clone of the primary display and it's resolution is limited to that of the primary display.
The external monitor should have a separate display (ie: the desktop should span across both exteral monitor and laptop LCD)
I am assuming here that the component select / rpm mentioned in this summary provides what is referred to as the 'intel' driver in the xorg.conf file.

Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, including Intel driver, which may have resolved this issue.
To be more precise, Intel has undergone a major rewrite during Fedora 10, 11 and 12 cycles, and whole driver is working a lot better now. Users who have experienced this problem are encouraged to retry with at least Fedora 12 Beta and see if the issue is still relevant.
Please, if you experience this problem on Fedora 12 Beta or up-to-date system running Rawhide, let us now in the comment for this bug, or whether the upgraded system works for you.
If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
We hope to see how many older bugs in Intel driver are still relevant today, in hope that most of them were fixed in rewrite process.
[This is a bulk message for all open Fedora 10 i810-related bugs (39 of them are still open). I'm adding myself to the CC list for each bug, so I'll see any comments you make after this and do my best to make sure every issue gets proper attention.]
This problem has been fixed. I don't know when it got fixed but I recently tested my fully updated F11 system and the automatic detection works out of the box (I had to do some manual twiddling to get the proper mode tho'). I'll check with F12 when it is released and report back with a new bz if there are problems.
thanks for all the work !!
