Re: KDE is slow
Since it is a USB device:Originally posted by umpirsky
just unplug it and reboot, or, us "sudo rmmod xyz" (where "xyz" is the name of the kernel driver) toUSB device 1-9 : ZTE WCDMA Technologies MSM (ZTE,Incorporated)

Re: KDE is slow
It's not USB device. It's on the board. How can I determine the driver name?
Ah, that USB device 1-9 : ZTE WCDMA Technologies MSM (ZTE,Incorporated) is

Re: KDE is slow
Ok, then. More than likely there is an option in your BIOS to disable the TV tuner OR to change itsOriginally posted by umpirsky
interrupt number. Try changing its IRQ port first, and if that doesn't work then disable it. IF there is no
option in the BIOS to disable the TV tuner another option, although drastic, would be to cut the trace
supplying power to the tuner section, solder wires to the severed sides and lead them to a toggle switch
you mount on the back panel of your computer. (Use a shielded wire pair and ground the shield to
chassis ground.) That way you can turn your tuner off and on.

Re: KDE is slow
Well, if you want to continue to use it from within Windows then disabling it in the BIOS is out of the question.Originally posted by umpirsky
What you'll have to do is open a konsole and issue
lsmod
Copy & Paste the output into your next message so we can look at what drivers you have loaded.
One or more of them will be for your TV tuner (v4l1 and v4l2 kernel modules and their dependencies).
Once we determine which ones they are we can use
rmmod whateverthenameis
to remove them.
And, we will have to blacklist them to prevent them from being reloaded the next time you boot.
We do that by adding the line:
blacklist whateverthenameis
to /etc/modules.d/blacklist.conf (use kdesudo kate /etc/modules.d/blacklist.conf to edit the file)
and then rebooting."A nation that is afraid to let its people judge the truth and falsehood in an open market is a nation that is afraid of its people.”

Re: KDE is slow
The ones I've marked in red for sure, and perhaps all of those marked in yellow.Originally posted by umpirsky
The key is determining which module is the "master", the one that calls all the others because it depends on them.
You can use
modinfo tveeprom
to get information about that module and to see what else it depends upon.
The module that has the most dependencies is probably the "master". If you chose the wrong one and try
rmmod thewrongone
you will get a message saying that thewrongone cannot be removed because anotherone depends upon it.
What that means is that before you can remove the master module you must remove the dependencies first.
modinfo will give you a list of the dependencies of each module.
Here is an example for a module in my list, videodev:
IF you have an onboard webcam we may have to reinstall some modules to drive it, if we accidentally remove them.Code:$ modinfo videodev filename: /lib/modules/2.6.35-25-generic/kernel/drivers/media/video/videodev.ko alias: char-major-81-* license: GPL description: Device registrar for Video4Linux drivers v2 author: Alan Cox, Mauro Carvalho Chehab <mchehab@infradead.org> srcversion: 251FD042803B0D483A085D0 [color=red]depends: v4l2-compat-ioctl32,v4l1-compat[/color] vermagic: 2.6.35-25-generic SMP mod_unload modversions jerry@sonyvgnfw140e:~$ jerry@sonyvgnfw140e:~$ modinfo v4l2-compat-ioctl32 filename: /lib/modules/2.6.35-25-generic/kernel/drivers/media/video/v4l2-compat-ioctl32.ko license: GPL srcversion: CDE9BA0F7AB6F1894AFF7A6 [color=red]depends: [/color] vermagic: 2.6.35-25-generic SMP mod_unload modversions jerry@sonyvgnfw140e:~$ modinfo v4l1-compat filename: /lib/modules/2.6.35-25-generic/kernel/drivers/media/video/v4l1-compat.ko license: GPL description: v4l(1) compatibility layer for v4l2 drivers. author: Bill Dirks srcversion: E98903C7627EBE32AD250B1 [color=red]depends: [/color] vermagic: 2.6.35-25-generic SMP mod_unload modversions parm: debug:enable debug messages (int) jerry@sonyvgnfw140e:~$

Re: KDE is slow
You can
rmmod cx88xx
and see what happens.
However, a better way would be to create a spreadsheet. Put all your modules down the first column AND then across the first row. At the intersection of each row/column put an X if the module in the row depends on the module in the column. Start rmmoding the modules with no dependencies that obviously are part of the TV tuner drivers. You know you've got them all when the one with the most dependencies can be rmmod'd without errors.
BE SURE to blacklist them in /etc/module.d/blacklist.conf before you reboot!"A nation that is afraid to let its people judge the truth and falsehood in an open market is a nation that is afraid of its people.”

Re: KDE is slow
