    Awful Screen Flicker Ubuntu 9.10

    Hi all,

    Until now, I never used Ubuntu 9.10 on my Desktop (HP Pavillion 753n) because of a HORRIBLE screen flicker problem I have with my integrated Intel chipset

    Relevant lshw output as follows:
    Code:
              vendor: Intel Corporation
              physical id: 100
              bus info: pci@0000:00:00.0
              version: 01
              width: 32 bits
              clock: 33MHz
              configuration: driver=agpgart-intel
              resources: irq:0 memory:e8000000-ebffffff(prefetchable)
            *-display

                 bus info: pci@0000:00:02.0
                 version: 01
                 width: 32 bits
                 clock: 33MHz
                 capabilities: bus_master cap_list rom
                 configuration: driver=i915 latency=0
                 resources: irq:16 memory:e0000000-e7ffffff(prefetchable) memory:ec100000-ec17ffff
    I tried reading this sticky but I'm afraid I may make some irreversable changes to my install. The instructions are just a bit over my current knowledge level at the moment.

    I have tried using the 'auto-tune' setting on my monitor to no avail, and setting the refresh rate to 75hZ does not help. I don't know if it is relevant or not, but in my monitor's on-screen menu, it is showing the Horizontal (rate?) to be 79 KHZ and Vertical to be 75HZ...is this perhaps the cause of my problem, two different rates on my monitor?

    To be more specific about the flicker, it is apparent in any text I am reading, as well as certain dark features on light colored backgrounds.

    Thanks for any help, and I'm going to go lay down and try to alleviate this headache I have from staring at this monitor *pops Advil pills*

    Thanks,

    I think this ended up just being a monitor issue, because I switched monitors and now there is no screen flicker, and since there were no replies I'm requesting this thread be closed.
