touchpad not working
by ambresh shivaji 21 Feb '11

Hi !! I have recently installed Fedora 14 on my HP Pavilion dv3 2332tx laptop and it has not detected the touchpad (that I checked using " xinput list ") though it's working fine on windows7 (preinstalled). Please help me resolving this problem. Best. -- Ambresh Shivaji IOP Bhubaneswar Fear does not have any special power unless you empower it by submitting to it.

extremely slow copy speed (50k/s)
by vinícius mota 18 Feb '11

18 Feb '11

Hello everybody, I have this very weird problem, that I have noticed some 2 or 3 days ago, and of a kind I have never heard before. I made a post in fedora.forum ( http://forums.fedoraforum.org/showthread.php?t=259047) but get no awswer since then, and now I have been advised to post here too. Briefly, the problem is that the copy speed between the partition in which I am running my Fedora and another partition where I store backup data is now 50K/s, which is extremely slow by any standart (it has been usually around 10M/s, almost 200 times faster). This is for exemple much lower than the copy speed between my computers in my lab and home, via internet, which is obviously absurd. I have been using Fedora 64 for many years, and this is the first time I have a problem that I cannot solve by myself, which is very frustrating. Let me proceed with the details. My laptop is a HP Pavillion Dv7 2080 ep, in which I have two disks of 250G each. One of the disks is partitioned between two operational systems, Fedora 14 64 and Windows 7 64, and the other disk contains the above referred partition where I store my backups (I call it backup disk). The problem happens when I try to copy anything from my home in Fedora to the backup disk, and also when, while using fedora, I try to move data within the backup disk itself. I first thought it could be a hardware problem in the backup disk. Then I login into the windows and made a copy of some AVI files (3G approx) to the backup disk, which went normally, within a few seconds, thus eliminating this possibility. I move data within the backup iself disk using windows also without any problem. I try therefore to make the inverse process, a copy from the backup disk into my home folder in Fedora. It went normally, copying 4 G also within few seconds, actually with an excellent speed of 50M/s. After searching in google, I saw some people also complaining of slow copy speed (although they had 7M/s, more than 100 times faster than what I have now), and one cause could be that the source file system (in my case the Fedora home folder) would be near its full capacity. I therefore eliminate everything that I could, around 15G, and now I have like 20G of free disk space, which I think is more than enough for everything. The problem, however, persists. Some people also said that it could be the type of files and/or amount of data. I therefore tried several kinds of files (from raw data files to AVI and RMVB regular video files), and several amounts of data (from single files with a few Megas to folders with 20G) and in all cases I had the same unacceptably low copy speed of 50K/s. Another possibility was checking the disk via the command line "hdparm", but since I am not an expert I could not identify anything wrong from its output. Anyway, here it is for both disks (/dev/sda and /dev/sdb): [root@localhost ~]# hdparm -Tt /dev/sda /dev/sda: Timing cached reads: 11320 MB in 1.99 seconds = 5681.38 MB/sec Timing buffered disk reads: 204 MB in 3.02 seconds = 67.52 MB/sec [root@localhost ~]# hdparm /dev/sda /dev/sda: multcount = 0 (off) IO_support = 1 (32-bit) readonly = 0 (off) readahead = 256 (on) geometry = 30401/255/63, sectors = 488397168, start = 0 [root@localhost ~]# hdparm -Tt /dev/sdb /dev/sdb: Timing cached reads: 12044 MB in 1.99 seconds = 6046.50 MB/sec Timing buffered disk reads: 206 MB in 3.00 seconds = 68.57 MB/sec [root@localhost ~]# hdparm /dev/sdb /dev/sdb: multcount = 0 (off) IO_support = 1 (32-bit) readonly = 0 (off) readahead = 256 (on) geometry = 30401/255/63, sectors = 488397168, start = 0 It seems therefore to be a problem in the software, caused by the updates, since until 10 days ago it was everything ok. However, I usually make the updates whenever they appear but make my backups much less frequently. Therefore I don't know for sure what has changed in Fedora through the updates since the last backup I made, when everything was working fine. He is the line of my /etc/fstab file which defines my backup disk, with the label common LABEL=common /home/vinicius/Desktop/common ntfs auto,user,sync 0 0 Thank you all for your attention and please apologise me for the huge text.

Dell Latitude 110L - Wireless reads as ethernet
by Micheal Parker 09 Feb '11

09 Feb '11

Greetings all, I am trying to get the built in wireless to work on a Dell laptop Latitude 110L with Fedora 14 - when I run ip addr I get output that wlan0 is link/ether - I believe this is my problem. I've check multiple forums and cannot find a trouble shooting procedure to resolve this issue. When trying to activate the wireless I receve a "cable not connected" error. The system reads it as wlan0 but the link/ether leads me to believe this is a configuration error with the wireless. Any suggestions or pointers in the right direction is appreciated. Tom
