Ubuntu 11.04 on HP Envy 17t-3000 laptop

Installing was a pain in the butt. The graphics would start flickering on modesets with the install kernel. After upgrading the kernel to 3.2.3 vanilla disabling modeset resulted in a black screen with a blinking cursor.

So, to install use the ubuntu-alt cd and do a text mode installation. (avoid the mode set epileptic fit inducing flicker.) After the install is finished within grub ad nomodeset to the kernel command line and / or remove the spash command line. Then after building 3.2.3 kenel and installing it change things by removing the nomodeset you added before and also remove the splash option. Now the system should boot ok to a usable home screen.

Also WRT graphics I have gone ahead and just blacklisted radeon as well. The radeon driver takes too long to boot and for my use I don’t really give a shit about having more graphics umph anyway.

Audio will not work (because the snd_usb_audio device confuses ALSA. Fix this by adding snd_usb_audio to the blacklist.cfg file in /etc/modeprobe.d diretory.

Now about the only thing not working is the clickpad.

hear I use may pad and work scripts.
pad:
#!/bin/sh
/usr/bin/synclient TapButton1=1 TapButton2=0 TapButton3=0 LBCornerButton=2 RBCornerButton=0 LTCornerButton=2 RTCornerButton=3 VertEdgeScroll=0 VertEdgeScroll=0 HorizEdgeScroll=0 CornerCoasting=0 VertTwoFingerScroll=1 HorizTwoFingerScroll=1 PalmDetect=0 EmulateTwoFingerMinW=100 AreaBottomEdge=3900

work:
#!/bin/sh
/usr/bin/synclient TapButton1=0 TapButton2=0 TapButton3=0 LBCornerButton=2 RBCornerButton=0 LTCornerButton=2 RTCornerButton=3 VertEdgeScroll=0 VertEdgeScroll=0 HorizEdgeScroll=0 CornerCoasting=0 VertTwoFingerScroll=1 HorizTwoFingerScroll=1 PalmDetect=1 EmulateTwoFingerMinW=100 AreaBottomEdge=3900

FWIW I have a Displayport to HDMI converter cable and it works very well for driving my external 1080p display.
