OpenSUSE Hardware :: 11.3 - USB Keyboard Error (Cannot Type For Few Secs)

Sep 13, 2010

I am using an external USB keyboard to my laptop. Suddenly (after using this keyboard for 6 months), some randomly times I need to press the button 6-7 times before something appears on screen. This happens randomly, I may be able to type a whole paragraph without problem, and suddenly I can't type anymore for few seconds. My system is opensuse 11.3 and it happened last friday 9/10 ( if it is related to any update). I tested the keyboard to another pc and it is working. I tested another keyboard to my laptop and I still have the same problem.

OpenSUSE Hardware :: Keyboard Won't Type Upper-case Characters?

Mar 14, 2009

Since yesterday I have been having a strange and fairly aggravating keyboard problem. For some reason I am sometimes unable to type upper-case characters. My shift key doesn't behave normally. If I type shift-C, for example, nothing happens; if I try it several times, sometimes the character will eventually appear, sometimes preceded by a ) character. What's worse, some key combinations, such as shift-I, kill the brightness on the screen. After this happens a couple of times, the mouse freezes, and only a reboot will restore it. This does not seem to be remedied by logging out of the session (either gnome or KDE) and into another session. The problem seems to affect both desktop environments.

This problem seems to be intermittent. For example, it seems to be working normally now, but about five minutes ago GNOME gave me a bug reporting window on boot and informed me that the keyboard-switcher panel applet had crashed. I have tried exciting to a console with ctrl-alt-F1 while my keyboard is behaving in this way, and have found that my keyboard does not work correctly in the console either.

I would normally use several keyboard layouts as I need to write in several languages, but I have turned them all off and reset the keyboard control panels to defaults in both environments, and I am still experiencing the problem.

OpenSUSE :: Getting Login Error When I Select Meego As Session Type / Sort It?

Jul 30, 2010

I installed goblin by run GoblinUI.ymp and logged out.
After I logged out, I chose meego as session type and tried to login again.
I entered correct password, but when I press enter after type password , display change to black and got some message and backed to login session again.

On the other hand, I succeed in running MeeGo Live CD(1.0.1 build 1.4).
I wrote MeeGo Live CD image on USB Flash Driver by using Win32 Disk Imager, and boot that one successfully, although it has some flaw.

Network Settings Window is stuck in workspace and can't move or close, so it cover other appication's window. Internet on toolbar is broken, so I have to run FireFox in application toolbar to use internet.

I'm using Netbook based on Atom CPU and GMA.OpenSUSE installed in my netbook is installed by KDE Live CD image.

Should I Use Gnome to use Goblin, because MeeGo is using Gnome? Or.... what is problem make Goblin doesn't work?

Ubuntu :: Keyboard Keys Type Different Letters?

Aug 8, 2011

Yesterday, after browsing for a while, my keyboard suddenly started to show different characters than typed. The keys are just typing different letters than pressed. For example, the j displays a 1, the k displays a 2, and so on. This only happens on the x server. On the terminal, before starting the x server, the keyboard works just fine.

I'm running Ubuntu 9.10.

Ubuntu Installation :: Can't Install 9.10 On PS3 - Keyboard Doesn't Type?

Jan 28, 2010

The title says it all. I'm trying to install Ubuntu 9.10 on my PS3, but the keyboard isn't typing. I can't complete the install, because I can't type anything. I've followed all the steps properly, everything goes smoothly, the mouse works just fine, and the capslock and numlock lights light up on the keyboard, and toggle when I press the corresponding buttons. The keyboard even works at the kboot prompt. After I choose the partition to use, I have to enter my information to continue. Without being able to type, I can't progress. The keyboard obviously works, since I can type just fine at the kboot prompt.This one's got me scratching my head. I'm going to try a 9.04 cd tomorrow, see if that works, but I was really hoping to get 9.10 on there.

Ubuntu :: Cannot Type Letters With Diacritical Marks Using Latvian Keyboard Layouts

Jan 13, 2010

I have added a Latvian keyboard layout to my Ubuntu 9.10 system (Russian as the system language). I cannot type Latvian letters with diacritical marks. I chose an apostrophe-based keyboard layout, so that I get the letter I need by pressing an apostrophe before. For example, to get ā, I would press 'a.The problem is, when I press ' followed by a letter or space bar, nothing appears on the screen. I continue typing as normal, but each time I press an apostrophe, the next character I press displays nothing on the screen. I have tried installing a Latvian language pack through System -> Administration -> Language Support. It was generally a useful addition. But it did not solve the problem. I still could not type Latvian. After that, I tried removing the Latvian layout from settings and adding it again. It did not help. I tried removing the layout, restarting my computer, and adding the layout back. The problem was not resolved.

I have tried different Lativan layouts (with tilde, with F, and standard). I had the same problem regardless of the layout I used. I browsed dozens of forum threads, and in one of them I found a workaround for this problem. For example, to type �, I hold down Shift and Control together, and while holding them press u0160 (because 0160 is a hex code for � in the character map). The first 0 is not significant, so to save time I type u160. I looked up the hex codes for the letters I need in Applications -> Accessories -> Character Map. In that application, at the bottom of the window, for each letter there is a code U+(four hex digits) e.g. U+012A. I wrote out all the codes I need on a small paper slip and stuck it to my monitor.Entering symbols this way is rather inconvenient. But at least it is possible.How to enter Latvian letters using just a Latvian keyboard layout? Is it a bug I should file? Would be great to find out.

General :: Cron Job Runs Every 30 Secs?

Jul 24, 2011

The problem is I need the php program to send member email confirmation which contains a confirm link. Run every min may still make the member wait. So I like to make it to run every 20 or 30 secs.

I don't want to put the code to send email on my sign up page as that's no good.

But I don't want to put a sleep 30 sec on my php script and going on loop. If it failed in the middle then it may wait abit to start.

What can be done to achieve my goal and what's the best way?

Making a php script to run as a daemon process? Is that possible and okay?

Server :: IP-Config: No Response After 60 Secs?

Apr 18, 2011

I have followed this guide [URL] to setup a diskless cluster based on ubuntu server. Every thing is fine in the boot process except this:

After the client boots vmlinuz and init.rd, I see some information and after a minute I see:

IP-Config: no response after 60 secs - giving up
/init: .: line 3: can't open /tmp/net-eth0.conf
kernel panic - not syncing: Attempted to kill init!

It is strange since it gets an ip address when it want to boot. I don't know what is wrong with it.

Ubuntu :: Desktop Freezes For 30 Secs When SD Card Plugged In

Jan 22, 2010

I am attempting to copy files to a 1GB SD card using my built-in SD card reader on my notebook computer. This function worked great on Hardy Heron. However, I switched to Karmic Koala about a week ago. Upon insertion of the SD card, the entire desktop (including mouse cursor) will freeze for about 30 seconds. Then, the SD card apparently mounts with an icon showing on the desktop. I can then open Nautilus and view the files and folders on the card. When I attempt to copy a file over to the SD card, the transaction looks as though it completes because the file icon shows up. However, Nautilus suddenly unmounts the card. When I check the file, I find that only half or less has copied over the the SD card.

Ubuntu :: Voip Call Cuts In 25 Secs Through Netgear Router?

Aug 16, 2010

I have a Compaq Presario V2000 running Ubuntu 10.04. I use voip to call international mobile numbers. I'm currently using a Netgear router (at a friend's place) and now, my calls cut in 25 seconds. The call time keeps running, but neither can hear each other after 25 seconds. I've tried using service providers like Actionvoip and Jumblo (as they are cheaper than Skype) and clients like Ekiga and Twinkle. Same It happens on both Wi-Fi and ethernet. There is enough credit I tried using my friends Dell Latitude running Windows 7 with my Jumblo account. Surprisingly, it worked perfect!Previously I used a D-Link router and it worked flawlessly with my system.I fail to understand if it is some settings issue or a bug with Netgear's firmware. If anyone else has come across this issue and has been successful in getting around it

Ubuntu :: Blinking Cursor For 12 Secs Before Login Screen Appears

Oct 20, 2010

I installed Ubuntu 10.10 alongside my Windows 7 os in a dual boot config. I used an installation disk and allowed the ubuntu installer to do all the resizing of partitions, installing of grub, etc. The install is working great and I haven't needed to boot my windows os since which is great. The only complaint I have is that it takes it takes a bit longer to boot than windows did for some reason. The culprit is a blinking cursor that comes up and remains for about 12-15 seconds before the grub menu appears. I already altered the boot option for the grub menu so that ubuntu is default and the option to select another os only appears for 3 seconds but I don't think this is related since the delay occurs before those options appear. I'm not really sure what is causing the delay. Is it looking for the loader? If so, is there a way to edit the configuration so doesn't have to search? As I mentioned, the install is running great otherwise.

Debian Hardware :: USB Serial Adapter Spontaneously Emitting Data Every 20 Secs

Jul 13, 2015

I tried connecting my Debian laptop to a vintage Apple //e using a Super Serial Card on the Apple side and a USB to serial adapter on the laptop side. It kind of works -- I can send data over to the Apple using e.g. echo "foobar" > /dev/ttyUSB0 or via minicom --, but every 20 seconds (quite exactly!) some 4 random characters appear on the Apple's screen (mostly tildes, sometimes a pipe). This does *not* happen when booting the laptop into Debian rescue mode; so I guess it must be some (daemon?) process messing around with the usb serial device in regular intervals.

I tried to disable quite some services, but the problem remains.I don't have any clue how I might catch the evil-doer in the act -- virtually all serial monitors I've so far read about allow only monitoring the interaction of a known program/process with a serial port. But in this case I first have to actually find out which process is talking to the serial port in the first place.
