Ubuntu :: GTX 460M: Clock Changes Make Screen Flicker?

Dec 6, 2010

My G73JW works really great except for 1 thing. A change in the performance level causes short black flickering on the display, which is absolutely inacceptable (e.g. with compiz). Setting the preferred mode to "performance" locks the performance level and helps but seems like a bad solution (batter life and heat).

Ubuntu :: Get Screen Flicker Randomly After Every 1 Min

May 13, 2010

I have downloaded the ver10.04. I am running it on my laptop with a NVIDIA GeForce GO 7600 128MB graphics card. I am using the NVIDIA driver on the system. The screen flickers randomly after say every 1 min. By flickering I mean it just refreshes and goes blank for say 1ms during the refresh. It happens even more if I turn on CompViz option.

Ubuntu :: Screen Flicker After Suspend / Hibernate?

Oct 4, 2010

All is in the thread title. When I log back in after suspend or hibernate I get a lot of flickering on the screen. I noticed (I think) that it calms down a bit when streaming video from the net, if that gives any clue...

I'm using a dual boot with Vista basic/lucid lynx on an Acer Aspire 5100 laptop.

Ubuntu :: Login Screen Flicker Then Get Normal

Mar 10, 2011

I am having a funky issue at login. When I enter my username/password at login with the GUI (I disabled the list of users some time ago) the screen will flicker then return me to the login screen. There is no notification of an error. It doesn't matter if I try the recovery console or safe mode there is the same issue when I try and login with this user. However, I can login with a different user open a console and su to that user that wouldn't login at the GUI.

Ubuntu :: Black Screen Flicker In 11.04 / Gnome3?

Jun 16, 2011

I'm getting the occasional full-screen black flicker on my laptop, it's an Asus G73JW with an nVidia 460M card, running the restricted drivers. I've installed Gnome3, and so far like it more than Unity, but the flickering needs to stop

I've also noticed that some animations aren't as smooth as they should be, like when I hit the top-left corner to bring up the dock it studders just a wee bit.

I have LucidLynx installed on my eeepc 1005PE. I am currently using it under the gnome interface but i also have the notebook version of it installed (probably because i got a notebook remix of it, not quite sure). All is well except for the following: after i power up my notebook, login and i can see the panel i plug the power cord in. And the my screen starts flickering in orangeblack colors. Nothing i do seems to take it out of this state but a good old hard-reboot.

Ubuntu Installation :: Dell Monitor Screen Flicker - How To Fix It

Sep 11, 2010

I was on earlier 9.x version of ubuntu with following configuration working perfectly: IBM ThinkPad T60 with ATI Technologies Inc Radeon Mobility X1400 VGA graphics card (found it from lspci) With an external Dell 19" monitor attached to it. I upgraded yesterday to Ubuntu 10.4 LTS and now the Dell monitor screen keeps flickering all the time! I always work with an external bigger monitor attached to my laptop as working for long hours on the smaller screen of the laptop gives me headache. The frustrating point is, this setting was working perfectly until I was on Ubuntu 9.x, I upgraded to 10.04 LTS and this has stopped working.

Ubuntu Installation :: Distracting And Unusable Screen - Flicker In 10.10

Oct 13, 2010

Screen flicker Ubuntu 10.10
After installing Ubuntu (Version 10.10 DVD �amd 64Ubuntu 10.10 live DVD).
On the following hardware
Gigabyte GA-K8VT800-RH motherboard
3GB ram
AMD Sempron 3400 cpu.
ATI Radeon X1600 Pro Video card. 256M ddr2 AGP VGA/TV0/DV1-1
p/no 882c85-03

The screen resolution looked very good with all screen resolutions working well The colours and fonts very clear. All other device drivers worked 100%. But unfortunately the display flashes about every 10 seconds and the partial beak up of the display only lasts a fraction of a second and very distracting and is unusable. Testing with Ubuntu 10.10 live DVD. With this months Linux Format Magazine also exhibits this problem. However deleting the partition and installing Ubuntu 10.04 Beta1 DVD -386. And all updates downloaded. Works 100% with no screen flicker.

Fedora Security :: User "jetty" Is World-readable - Screen Started To Flicker Some Time ?

Oct 3, 2010

This morning I ran sectool (in terminal for the first time. Before that I used sectool-gui) and I got this (written to file)...

See attachment please..

I think... the user "Jetty" may be a part of (or has something to do with SQL?).. This machine I have is not a server (in fact I know pretty much nothing about web servers).. this machine is used purely for local app development (python PyQt4/ and C++/wx - making games, general utilities, specialized calculators...etc)

So... Can anyone please tell me who the user "Jetty" is ? (The others are safe, I compiled python/SIP/PyQt4/wx/aliens from source... so that;s probably why it doesn't belong to packages.

Plus, My screen started to flicker some time (could it be possible someone is messing w/ my xorg configs?)

Ubuntu Installation :: Screen Flicker During And After Installation

Jun 15, 2010

I've just installed Ubuntu 10.4 alongside Windows. During the installation process, everything was black, then it flickered for a couple of seconds, then went black again. This happened many times. After the installation, I was hoping it would stop, but the same thing happens at the login screen. It flickers for a couple of seconds, then goes black. I figure it has something to do with my display drivers, but I don't know how to install them without using Ubuntu. If it makes any difference, I have an ATI Radeon 4890 video card.

Ubuntu :: Need To Make System Stop Updating BIOS Clock To UTC Time

Jan 22, 2011

I have Ubuntu 10.04.1 32bit installed on my flash drive so wherever I go I can have my own mini personal computer, but one problem I'm having is every computer it is run on the next time it's rebooted to the OS on the hard drive it has UTC time instead of the actual time for the timezone you're in that Windows uses. So is their a way I can make Ubuntu not automatically change the clock to what it wants?

Ubuntu :: Changing GPU Clock Speeds Results In Black Screen?

Sep 13, 2010

I've recently done a clean install from Karmic to Lucid, everything went well first time, although I noticed that my GPU performance seemed to drop. It wasn't amazing to begin with being an older AGP card (nvidia 6800GT), but it was enough of a drop to make me look for a solution.

I thought maybe the drivers in Lucid were to blame so I recently added the ubuntu-x-swat PPA


to get the most up to date drivers.

Performance didn't go up, so I tried the 173 version of the drivers to see if that would help, but I had no luck.

Today I'm pretty sure I downloaded an update from the above PPA and since then every time I change the clock speeds (via the Coolbits option within nvidia-settings) on my card I get a black screen, there is no response from any input device and I have to hold the power button to turn off the PC.

I want to know if there is anyway to check recent packages I've downloaded, and also if anyone could shed some light as to why changing the clock speeds of the card would result in a black screen and no response from the keyboard or mouse.

I'd also like to point out, that I've been changing the clock speeds of the card since I first installed Karmic with no problem. Additionally before I downloaded today's updates, even with the new packages from the above PPA changing the clock speeds worked perfectly. It seems that something I downloaded is to blame.

Ubuntu :: Conky Clock And Top Panel Clock Not In Sync

May 27, 2011

I'm using a very simple conky script to diplay the date and time on my desktop. I've noticed that he conky clock is a few seconds early compared to the time displayed in the right hand side of the top panel (Natty). I guess both displays are based on the same "internal" time, so I'm left wondering how this could happen, and how to sync back the clocks.

It seems that Conky is in sync with the system date, while the panel clock is 2 seconds late (on my system). Checked with while true; do date; sleep 0.1; done

CentOS 5 :: Get Rid Of Virtual Clock And Use Physical Clock?

However, the time showing in os using date command differs from bios time by roughly 4 hours. I am running ntp services which sync the time with another centos server on the network. It appears that some services are using virtual clock and some use physical clock. How do I get rid of virtual clock and only use physical clock?

Programming :: Make An "alarm Clock" With Mpd And Gxmessage?

Feb 21, 2010

I'm trying to make an "alarm clock" with mpd and gxmessage. Gxmessage allows you to assign unique exit codes for its buttons to use in your script. This is what I have so far:

mpc clear
mpc load alarm


Now I know I'm way off with the case statement, because when the alarm_message function is called within the case, both of the exit codes I assigned to the buttons (-buttons "Stop":1,"Sleep":2 ) return to their default value.

What I would like is for every time the "Sleep" button is pressed, it would pause mpc, sleep for an amount of time, play, then open gxmessage again to restart the case statement (retaining the exit codes I assigned to the buttons). Am I on the right track?

Ubuntu :: Default Panel Clock Shows Up On Middle Of Screen When Moved To Bottom Panel?

Mar 4, 2011

I have had this problem with all installations of Maverick Meerkat. Moving the default clock from the upper panel to the lower panel makes it bahave strangely. When clicked on, it now appears in the middle of the screen (sometimes even higher depending on resolution). This never happened prior to Maverick Meerkat.

How do I go about to fix this strange bug?

Ubuntu :: 9.10 Box - Getting Flicker While Viewing Flash Contents?

Apr 27, 2010

Anyone using flash with blogtv? I've got a Ubuntu 9.10 box with a nvidia 9400gt card running flash and have run into some weirdness. I get alot of flicker when viewing flash content on sites like blogTV. Also, cannot get my webcam going in blogtv. Webcam is a webcam pro 9000 and works flawless. The problem is adobe flash. I have researched and know that there are problems with flash and linux but whats interesting is that I also run a fedora 11 box and blogtv works fine. The video card in the fedora box is a nvidia 8400 and running flash.

On the Ubuntu box when you go to broadcast you get the flash permissions (allow blogtv permissions on camera) but the buttons do not work. It pretty much locks up in the flash widow only. Also, Viewing content on the site has a lot of flicker. Other sites do not have this flicker. Seems strange that my fedora box works with no problems but the Ubuntu box doesnt. Today Im going to try the beta flash (libflashplayer.so) from adobe version and see what that produces.

Ubuntu Multimedia :: Line Flicker During Video Playback?

Apr 3, 2010

I've installed Ubuntu 9.10 and the prime reason for giving it a go is due to the media center capability with apps such as Moovida and LinuxMce.

Unfortunately during video playback [either divx or flash] there appears to be a random line or lines which flickers on the screen when the video is in fullscreen mode.

I'm using an ATI x1900 video card and have tried using both Tote and VLC, and I have also tried installing the fglrx.

But, both with and without flgrx installed, under the section 'Device' in xorg.conf it says that the driver is 'vesa'.

I don't know how to disable the default ATI driver to enable fglrx, or whether I am going off on completely the wrong tanget and should be looking at something else.

Or is there better support for my type of card in Ubuntu 10 as I don't want to go back to Ubuntu 8 which is the last supported version of the os that ATI developed a driver for my card.

Ubuntu Multimedia :: 10.10 Ati X1250 Games - 2D+3D - Flicker But Run Smoothly

Oct 29, 2010

After having a lot of issues with my card on Ubuntu 9.04, I sadly, removed it an installed XP over it. (XP is better than Vista at least, which is what came with my Laptop, I'm still recovering from THAT traumatic experience.) I have an Acer Extensa 4420, which has a Radeon Xpress 1250 Graphics Card. I tried it again with Ubuntu 10.10 and am very pleased, I run Compiz/Desktop Effects just fine, everything is smooth and fast, and most applications run fine.

As of right now, there are two games which will not run properly. Tibia, and Frets on Fire. Both of these (Tibia is 2D Sprite based, Frets on Fire appears to be 3D but might be some sort of isometric 2D variant). They work, but PARTS of the screen flicker. In tibia, the "game window" is fine, runs at a constant 30fps (not bad, it's a slow card after all), but the chat window and inventory windows flicker at a random rate, but usually once or twice per second. On Frets on Fire, it's the colored dots that scroll on the screen, and the stage lights (though those might intentionally flicker, but they seem to follow the pattern of the dots so I'm gonna go with the idea that it's a problem.)

I tried FGLRX for grins, Compiz/etc. still worked but then nothing that used any type of hardware acceleration would even open, so I removed it. Are there any other drivers for the X1250? It's a legacy product, unfortunately. And as ATi is in this war with nVidia right now, with their new 6xxx cards coming out, I don't see any support for my old (it was old when the laptop was new) integrated GPU coming from them.

How can I make it work? Not looking for major 3D gaming here, but I would like those to work!
