How to access developer tools in chrome


Check the settings within the dev tools and make sure you have "Show 'Emulation' view in console drawer" option checked under the Appearance heading.

After that, open the console (Control+~) - click on the emulation tab and you should be able to emulate a mobile device.

Hope that helps!

Get the detail of the problematic driver in the Device Manager (and post it here please):
[Start] Control Panel, System, Device Manager, [Component Name], [Component with Exclamation], [Right click], Properties, Details tab, Property pull down; chose Hardware Ids and write down the VEN and the DEV sections in the Value's box (including the VEN and the DEV words)
Please do not download drivers from questionable websites because it may contain malware.

I need Fedora 15 drivers for a MultiTech MT5634ZBA modem... ugg.


You must have the most recent kernel, 2.4.2 or higher. You will also need specific modules for installation, they are explained below. The MT5634ZBA-USB has been tested successfully in Mandrake 8.1 and RedHat 7.2. Please read the whole document, as some steps depend on how the Linux system was built. You need to select the USB Modem (CDC ACM) support kernel option. If you build as modules, you need to install the acm.o option. You need to set up the device node entries for the various modems. You can use up to 32 modems with this driver. Use the following commands to set up the first four: mknod /dev/usb/ttyACM0 c 166 0 mknod /dev/usb/ttyACM1 c 166 1 mknod /dev/usb/ttyACM2 c 166 2 mknod /dev/usb/ttyACM3 c 166 3 You should now be able to use a terminal emulator program to attach to this device and connect to your modem or other terminal device. If your current version of Linux has the ACM driver compiled into it, then you're ready to roll. If it has the driver built as a module, then you'll have to enable the driver with the following command: modprobe acm At this point, you may have to unplug the modem's USB cable and then plug it back in (this isn't necessary if you're using kernel 2.4.X). You should see the modem's lights come on. If you see some activity lights on the modem, type the following: lsmod This command will display a list of loaded modules. The ACM module should be displayed as loaded. Now that you've got the driver loaded, you need to set up the device node (in /dev) for the modem. You can use up to 32 modems with this driver, but most people will only need to configure one. To set up a modem, use the following command: mknod /dev/usb/ttyACM0 c 166 0 You should now be able to use a terminal emulator program to attach to this device and connect to your modem or other terminal device. Going one step further, you can set up a symbolic link from /dev/modem to the ACM modem device. This is accomplished by using the following command: ln -s /dev/usb/ttyACM0 /dev/modem That way, KPPP and related applications can all refer to the modem as /dev/modem without caring what type of modem it is. Models: MT5634ZBA-USB If the above document doesn't get you going, send me a private email & I'll have a Multi-Tech Systems, Inc. Technical Support Rep. get in touch with you ;-)

Is it possible to access the whole C drive when using Ubuntu?


What Can Be Mounted

The most common thing to be mounted is a hard drive partition. Hard drives are kept in /dev and have different names depending on what type of drive they are. IDE/ATA drives are labelled as /dev/hda, /dev/hdb, /dev/hdc and /dev/hdd (since a PC's IDE interfaces can only handle 4 devices at a time). Note that these can be devices such as IDE/ATA CDROMS, Compact Flash to IDE converters, and some special floppy drives (although they tend to appear mainly in laptops). For SCSI devices the labels are /dev/sda, /dev/sdb, /dev/sdc, /dev/sdd, /dev/sde, /dev/sdf, /dev/sdg, /dev/sdh and /dev/sdi (since a SCSI chain can contain up to nine devices). Other types of drive, such as USB, SATA, etc. are mapped to these SCSI devices by Linux. Therefore SATA and USB drives are labelled as /dev/sdX where X is a letter, starting at "a".

Since these are literally the devices you can issue a command such as:
sudo eject /dev/hdc

If /dev/hdc is a CD drive then it will eject.

In the case of hard drives, there is another abstraction. A hard drive (and many devices such as USB "sticks" which act like hard drives) can be partitioned to allow many filesystems to be stored on them. This means that the filesystems themselves are accessible via the partition labels, such as /dev/hda1 (the first partition on /dev/hda). This means that we finally know about something we can mount, a partition, since it contains a filesystem.

Another physical filesystem which can be mounted is the ISO9660 filesystem used on CDROMs. Since there is only ever one CD in a CD drive there is no point creating /dev/hdc1 (where /dev/hdc is a CDROM drive) since there is only one filesystem on it. That means that you can mount CD drive devices explicitly, so if /dev/hdc is a CDROM drive then it is possible to mount /dev/hdc if there is a disc in it.

Floppy disks only contain one filesystem, and are labeled as /dev/fd0 for the first drive, /dev/fd1 for the second drive, etc. So now we know three things which can be mounted.

Devices like USB sticks are treated like hard drives (so /dev/sda1, for example, may contain a filesystem) and so are iPods (although I think the main data on an iPod is stored on the second partition)

Mounting is not restricted to physical devices. If you have a filesystem "image" (which IS a filesystem, whether an exact copy of an existing filesystem, or a filesystem created specifically for that file) then you can mount that through the use of a fake device called the "loopback device"


How To Mount/Unmount Filesystems


Unmounting

Firstly I will tell you how to unmount any filesystem you mount after trying these commands. Unmounting is done through the "umount" command, which can be given a device or a mount point so:
sudo umount /mnt
sudo umount /dev/hda1

Would both unmount the filesystem on /dev/hda1 if it is mounted on /mnt.

Remember that a filesystem cannot be in use when it is unmounted, otherwise umount will give an error. If you know it is safe to unmount a filesystem you can use:
sudo umount -l /mountpoint

How to enable the serial port under linux(ubundu 10.04) tell me commands for what are all the to solving the problem: i need immd answer


Linux offers various tools. Linux uses ttySx for a serial port device name. For example, COM1 (DOS/Windows name) is ttyS0, COM2 is ttyS1 and so on.
Task: Display Detected System's Serial Support

Simple run dmesg command
$ dmesg ' grep tty
Output:
[ 37.531286] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A [ 37.531841] 00:0b: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A [ 37.532138] 0000:04:00.3: ttyS1 at I/O 0x1020 (irq = 18) is a 16550A setserial command

setserial is a program designed to set and/or report the configuration information associated with a serial port. This information includes what I/O port and IRQ a particular serial port is using, and whether or not the break key should be interpreted as the Secure Attention Key, and so on. Just type the following command:
$ setserial -g /dev/ttyS[0123]
Output:
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: 16550A, Port: 0x1020, IRQ: 18 /dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4 /dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3

setserial with -g option help to find out what physical serial ports your Linux box has.
