Airview2-Ext on Fedora 11

[BTSOOM]

Has anyone gotten an Airview2 to work on Fedora 11?

I've installed the Airview SW on Fedora 11 and on execution, the video is corrupted (black window with vertical columns of "tildas"). An error window appears with "Airview Device Error" in the title bar. I can't read the error due to corrupted video.

Prior to installation of the Airview SW, I did the following:

- Installed Sun JRE6 Update 17
- Added UUCP to the user account (there was no LOCK group in Fedora)
- Added a script for udevinfo (per the Ubuntu 9.10 posting)

As a test I rebooted the same PC into Windows XP, SP3 and installed Airview2 SW. In WinXP, Airview2 works great! So the Fedora 11 problem is not a hardware problem, but is related either to the SW or an error I've done during setup.

Any help would be appreciated.

Hmmm... Fedora 11. Well, I've tested AirView with Centos 5.4, which is a RHEL5 offshoot, like Fedora is supposed to be, but who knows. It could very well be that our friends in the Fedora world have thrown a new twist into the mix that the JVM doesn't like, but I sorta doubt it because what you're describing sounds like a video card & driver issue. Corrupted video of any kind usually spells video/driver issues.

You sure you've got the proper video drivers installed for your specific set of hardware?

Have you checked to make sure your Xorg config is correct? (gotta check with the Fedora forums for details of that one)

Whatever your Xorg config driver is set to, try switching the driver to "vesa" and see if you still get the same error.

In /etc/X11/xorg.conf look for section:

Section "Device"
Identifier "Videocard0"
Driver "intel"
EndSection

Change the "Driver" line to "vesa", instead of whatever you've got there and see if that still does the same thing.

Unfortunately I don't have a Fedora 11 installation here handy to give you a definitive answer, but give that driver change a try to see if that's the issue. Let me know.

Thank you for your response.

I think you are right about the Xorg driver. Unfortunately, Fedora 11 doesn't have an xorg.conf file! My laptop has Intel 85255/855GM integrated graphics which requires a version of the xorg-x11-drv-intel.xxx driver.

I have googled Fedora 11 video problems and it appears that Fedora 11 uses version 2.7 of the driver which yields corrupted video for some applications. Version 2.8 apparently fixes some problems, but it's not available for Fedora 11. Fedora 12 was just released and uses version 2.9 of the driver. My plan is to upgrade to Fedora 12 and see if that fixes the video problem.

When I complete the upgrade, I'll post back on this forum with the results.

Good news! Upgrading to Fedora 12 fixed the problem. To be clear, under Fedora 12, I did the following:

- Installed Sun JRE6 Update 17
- Added UUCP and LOCK to the user account
- Added a script for udevinfo (per the Ubuntu 9.10 link in the the release notes)

After these preparations, executing airview.sh as root worked.

Excellent, I'm glad you got it working, but 2 things...

1. With v1.0.11 you no longer need the udevinfo script fix. The release notes section that talks about that fix is for v1.0.08. If you've downloaded v1.0.11 (latest as of date)you gotta look at the notes for that version (towards the bottom). So you can remove the script. This version now makes use of the existing udevadm command.

2. With inclusion of your own user ID in uucp and lock groups you don't need to run AirView as root. The whole point of including your userID in those groups is so you can just launch AirView with your own userID and not root. Clean out your /home/userID/ubiquiti-networks directory (remove that dir), and then re-launch airview.sh using your own user ID and let me know if it works. It really should.

All in all, I'm very glad you got it working.

Thanks for your response. Here is what I've discovered:

1. You are correct that the udevinfo script is superfluous. I deleted the script (by renaming it) and I can execute airview.sh normally (as root).

2. However, when I delete the ubiquity-networks directory and then execute airview.sh as a userID, the program issues an error message "Cannot find airview usb device....." If I then exit the program and become root, airview.sh executes normally.

I have verified that userID is included in groups uucp and lock. The installed version of the SW is Airview-Spectrum-Analyzer-v1.0.11.

Perhaps Fedora 12 has an unusual way of handling USB devices???? I have used external USB drives on Fedora 12 with no problem (i.e. I can mount, access and unmount them from userID).

Thank you for you help.
