[Windows 8] usable ext4 driver? topic






I am using a multi-boot system with Ubuntu 14.04 as my main system.
From time to time, I need to run Windows 8.1 or Windows XP for some special tasks.
My data are on 3 NTFS partitions, I did not experience issues accessing them from Linux or Windows.
Except - NTFS gets slower with the time, needs defragmentation, occasionally.

So, I was contemplating to use ext4 for my data.
For access from Windows there are drivers like Paragon ExtFS or Ext2Fsd.
I have, for test, tried Paragon ExtFS (v2.73) with Windows 8.1, but the experience was devastating: While reading went ok, writing corrupted the ext4 file system. With some fsck work most data could be recovered, but the capacity of the partition decreased each time.
Maybe the actual Paragon ExtFS (v2.395) is better; but before I try, maybe some of you have already tried?
There is also Ext2Fsd, is that driver better?

If someone has experience with such a setup, please share.






Encrypted Channel Issues - Ceton topic






I have been able to get the Ceton card working with the un-encrypted channels with the install of a cable card. I worked with the guys at the cable company and they have turned on their 'premium' channels for me which include most of the basic channels in HD but they are encrypted. I have tested to make sure they are working within windows media center, but I cannot get them to work on Myth. I receive an error that reads 'Could not read first 2048 bytes...' - From reading around I have read that several people have had luck with the encrypted channels and some say that the cable card wasn't 'setup' correctly.

From the Ceton I see that the for example HistoryHD has the copy flag set to 'One copy' rather than 'copy freely' like the clear channels. Also, I can see that myth does change the channel but in the logs I see 'Channel is scrambled, expecting CCI'

Any help from the experts would be greatly appreciated!






[ubuntu] printer trouble topic






Hi


I am using Ubuntu 14.04.


I made an error trying to upgrade a programme (tried to intall a 32-bit package on a 64-bit system, could that be it?) and as a result several things broke (related to python?). My installation of Google Chrome seemed to have disappeared, as did my printer. I got Chrome back. And now I can see my wifi printer online (SyncThru Web Service) and print a proper testpage from there. But if I try to print from a regular programme, the printer (Samsung Xpress M2825DW) appears in the print dialogue, but the machine just spits out endless white pages with code on them.


I cannot use system-config-printer ('fail to connect to CUPS server', 'CUPS print spooler does not appear to be running', etc) to reinstall the printer or check the settings.


Could someone possibly walk me through some steps to try to fix this? I have been using Linux for 10 years but am not a very technical person.


thanks






LVM Setup on an already installed Ubuntu gnome server topic






Hello everyone, I'm trying to set up an LVM on my File sharing server. The server has ubuntu 14.04 lts 64 bit running on a pentium dual core E2140 @ 1.60Z GHz with 1gb of memory (will be getting upgraded to 2 gb). The server is also running the latest version of Gnome. For drives right now I have 7 drives in the server:

Model: ATA IC35L04AVVA07-0
Size: 31.50 GB
Path: /dev/sda
File System: NTFS

Model: ATA IC35L04AVVA07-0
Size: 31.50 GB
Path: /dev/sdb
File System: NTFS

Model: ATA WDC WD400BB-60DG
Size: 37.27 GB
Path: /dev/sdc (this is the OS hard drive)
File Systems: sdc1 - ext4 sdc2 - extended sdc5 - linux-swap

Model: ATA Quantum Fireball
Size: 19.01 GB
Path: /dev/sdd
File Systems: sdd1 - extended (unallocated)

Model: ATA ST3250310AS
Size: 232.83 GB
Path: /dev/sde
File System: NTFS

Model: ATA WDC WD3200AAJS-6
Size: 298.09 GB
Path: /dev/sdf
File System: NTFS

Model: WD I HDS72 External
Size: 465.76 GB
Path: /dev/sdg
File Systems: sdg1 - extended New Partition #1 - lvm2 pv

I have no cd roms in the tower and no usb flash drives to do a live cd boot. what I want to do is first setup the group with sdd and sdg and move the files from the other drives to it (except the os drive) then I want to add the other drives to the group making it act as a drive with a little over a TB is there any way to do this without having to do a clean install or boot from a live cd? (I really don't want to do a clean install it takes a long time to get everything running correctly) if any other info is needed please let me know and I will get it for you. Thank you for your time and help :-) Christopher J. Crandall






Switching access points from command line? topic






I'm using a Transcend WiFi SD card in a camera, which behaves as an access point (essid WIFISD).

I've been switching from my router (essid dd-wrt) to the WiFi card using the network manager applet so I can download images, but would like to do it from a command line, so I can automate the procedure.

I've had a fiddle with iwconfig without any success, and I'm not even sure if this is the way to go.

Does anyone have a suggestion of how I can switch between the access points from a command line, please?

Why do I need a ubuntu one account to download apps topic






While the usual tradition of linux distributions is to have repositories accessible to anyone, why do I need to have a ubuntu one account in order to download apps on the ubuntu store? While ubuntu has until now been very strong into providing open alternatives to mainline products, e.g. from microsoft or apple, this requirement is a serious threat to the open philosophy. I can't see any technical difficulty into not having accounts on the server side, and I am very worried about this.






[ubuntu] The system is running in low-graphics mode only when logging off user topic






I’m working on setting up Ubuntu 12.04.5 in a classroom environment here in San Antonio, Texas. We hope to replace several labs currently running Windows XP that connect to a Citrix farm. This version of Ubuntu was selected to be compatible with NetSupport software that teachers use to monitor a classroom.

The OS is installed on HP dc7700u and dc7600u computers. I followed online directions for creating a Windows 7-style Ubuntu desktop (looks and works very nice too). There are two user accounts on this system, one for Students without the rights to install applications (all games removed) and the other for Administrators with full access. On boot up, the Student ID is logged in with the option to not require a password (as seen below).




After having everything almost at the testing stage I came across a problem. I get a graphics error when I log off the student user to try to use the Administrator account. Up until this point, everything has been running great. As soon as I log off, the system locks up with “The system is running in low-graphics mode”, input device settings could not be detected correctly. The next option is “What would you like to do?”

  1. Run in low-graphics mode for just one session
  2. Reconfigure graphics
  3. Troubleshoot the error
  4. Exit to console login


In most cases the mouse and keyboard do not work. A couple of times when I could make a selection I have tried all options but nothing happened. I can power down the system and it boots into Student user without any problems.
