Description Suzanne Logcher 2009-06-01 20:30:30 UTC 
Description of problem:
Running RHEL 5.3 CSB on Lenovo Thinkpad T61.  It's happy at 1440x900 res.
I got a ViewSonic VA2226w and it really wants to be at 1680x1050.  Unfortunately it looks like I'm unable to have different resolutions on cloned screens.

Version-Release number of selected component (if applicable):
RHEL 5.3 CSB

How reproducible:
ViewSonic VA2226w is blurry at 1440x900.

Steps to Reproduce:
1. Set res to 1440x900.
2. Observe T61 res is good.
3. Observe VA2226w is not so good.
  
Actual results:
See 3.

Expected results:
Would like to be able to set T61 res at 1440x900 and VA2226w res at 1680x1050.

Comment 1 Suzanne Logcher 2009-06-01 20:57:01 UTC 
Now that I entered the bugzilla, I learned of a work around in our own Desktop QE team.  Here's what I did:

1.  I had to change my laptop to not suspend when lid is closed and still in docking station.
2.  Close laptop lid.
3.  Restart X - ctrl-alt-bspace.
4.  Run xrandr to see the 1680x1050 res.
5.  Run xrandr -s 0 (or whichever number it is) to set it to the 1680x1050 res.

Monitor is all good.

When undock,

1.  Open laptop lid.
2.  Undock laptop.
3.  Hit laptop's func-F7.

Laptop is good.

To redock,

1.  Dock laptop.
2.  Close laptop lid enough to shut off laptop internal monitor but still access keyboard.
3.  Hit laptop's func-F7.
4.  Close laptop lid.

Monitor is all good.

Who knows what will happen when restart X undocked (on laptop).

My new cleaner work around for redocking was to setup this:

1.  Right click on top panel and click on "Add to Panel".
2.  Select "Custom Application Launcher" and then "Add".
3.  In Create Launcher, added this app:
      Name: Fix Resolution 
      Command: xrandr -s 0
    and picked an icon for it.

I will now run this app when I redock and need to fix the resolution of my monitor.

That's sort of the definition of cloning.  What behaviour are you expecting here?
Comment 4 Suzanne Logcher 2009-08-07 15:53:15 UTC 
Sorry for not replying sooner.  I've been fine using func-F7 when docking/undocking which adjusts the resolution accordingly.
