Comment 52 for bug 883319

I applied Mr. Bagwell's patch to Fedora 17 after receiving some guidance from Mr. Weir. I thank all who have posted for their contribution in resolving this long term regression.

My specific steps were...

1. Obtain the source: yumdownloader --source xorg-x11-server-common.i686

2. Extract the RPM to a subdirectory structure (in my case, ~/source/xorg-x11-server-x.xx.x-y.fc17.src)

3. Extract the xorg-server-x.xx.x.tar.bz2 file (contained in the directory created in step 2) to source subdirectories of that directory (in my case ~/source/xorg-x11-server-x.xx.x-y.fc.src/xorg-server-x.x.xx) created in step 2.

4. Modify the rrcrtc.c source code in the randr subdirectory (~/source/xorg-x11-server-x.xx.x-y.fc.src/xorg-server-x.x.xx/randr) as Chris states. I had to apply the patch manually, however it's very straightforward.

The following steps were issued from within the xorg-server-x.xx.x subdirectory created in step 3 above and presume you have all required development tools installed.

5. Command: ./configure --prefix=/usr.

6. Command: make

7. Command: sudo make install

I performed these steps on version 1.12.2-2 as well as on 1.12.2-4 and after testing each patch, I reinstalled (yum reinstall xorg-x11-server-common.i386) standard code to verify repeatability. In each case, scanning/panning was enabled following application of the patch.

I am running this on an Acer Aspire AOD257 which has (of course) an integrated trackpad. One issue I have noticed is that after application of the patch, the trackpad scrolling functions are disabled. That is to say, the trackpad continues to function as a "mouse", but the "finger drag along the right side of the trackpad" no longer functions. Under touchpad-system settings (KDE desktop), the touchpad information indicates "device not found". I cannot explain the relationship between this function and the patch, but will do more testing -- has anyone else on a netbook noticed this condition?
