Acer Aspire One 725 - missing graphic card driver?

- by Melon

Recently I bought an Acer Aspire One 725 Netbook and installed Ubuntu 12.10 on it. I bought it, because it can run HD movies and has Full HD on external VGA port. However, movies from youtube have a really slow framerate. If you open three tabs in Opera (for example g-mail, youtube and askubuntu) it gets really laggy. My suspicion is that the driver for graphic card is missing. When I check the System->Details->Graphics the driver is unknown. After running lspci | grep VGA I get this output: 00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Device 980a From what I see, I have a AMD C70 processor integrated with (or something similar) AMD Radeon HD 6290. Has anyone had the same problem? Do you know which drivers need to be installed for the graphics to work properly? On official Acer page there are only drivers for Win7 and Win8... Update: I have tried installing fglrx but I get the following error (either I don't have libraries or someone didn't make a clean build before release ;) /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c: In function ‘KCL_MEM_AllocLinearAddrInterval’: /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:2124:5: error: implicit declaration of function ‘do_mmap’ [-Werror=implicit-function-declaration] /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:2124:13: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c: In function ‘kasInitExecutionLevels’: /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:4159:5: error: ‘cpu_possible_map’ undeclared (first use in this function) /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:4159:5: note: each undeclared identifier is reported only once for each function it appears in /lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:4159:5: warning: left-hand operand of comma expression has no effect [-Wunused-value] Update 2: After fixing the erros in compilation, ubuntu acts bizarre and unstable (no left icon panel, no upper panel, cannot run any programs, I only see desktop)

Wifi not working on Acer Aspire One D270

- by Dani

brand new baby linux user here, never used Ubuntu or any other linux OS before, so be gentle and use short words! I installed Ubuntu 12.04 on my new Acer Aspire One D270-F61C/KF netbook (it's a Japanese computer which had Japanese windows preinstalled, and I decided to take the plunge and try Ubuntu because English Windows costs the earth and stars). Wifi isn't working; I enter my wireless password, it tries to connect for a while, then asks for my password again. And KEEPS ASKING, every few minutes. Wired connection works fine. Wireless card is a Broadcom BCM4313; I have the "additional drivers" checked and installed (I tried unchecking and then reinstalling them in case that would help, no joy, and now my home wifi connection isn't showing up in the list of available connections, argh). I've done a lot of googling and I gather there's a lot of issues with Broadcom cards, but some of the answers are for earlier ubuntu builds and many of them are a bit confusing for a new user. I gather I need to try installing some new drivers other than the proprietary ones provided, but I'm having trouble figuring out how that's done. Anyone got some simple, step by step instructions for me? Please bear in mind, TOTAL N00B. (EDIT): OKAY, got it fixed finally; after suggestions on the Ubuntu forums and messing around with drivers, what finally worked was installing Wicd. Not... using Wicd, for some reason, just installing it fixed it. ...I CHOOSE NOT TO QUESTION IT.

Restore Failure from Ubuntu One

- by Qawi Robinson

Had to do a reinstall of Ubuntu 12 after 13.10 failed. Lost all my data, but I remembered that I had data backed up to Ubuntu One. It recognized my previous backups but I got errors and a restore failure when I went to restore the data. This is what I got. Can anyone make heads or tails of this? I still don't have my data. Thanks.

SQLite with two python processes accessing it: one reading, one writing

- by BBnyc

I'm developing a small system with two components: one polls data from an internet resource and translates it into sql data to persist it locally; the second one reads that sql data from the local instance and serves it via json and a restful api. I was originally planning to persist the data with postgresql, but because the application will have a very low-volume of data to store and traffic to serve, I thought that was overkill. Is SQLite up to the job? I love the idea of the small footprint and no need to maintain yet another sql server for this one task, but am concerned about concurrency. It seems that with write ahead logging enabled, concurrently reading and writing a SQLite database can happen without locking either process out of the database. Can a single SQLite instance sustain two concurrent processes accessing it, if only one reads and the other writes? I started writing the code but was wondering if this is a misapplication of SQLite.

How should I manage my time?

- by Tathagata

There are times when just one bug that keeps eating away your time like hell ... for example this one. I generally end up wasting hours and realize I've gone terribly behind my schedule and not completed other tasks. With n number of tabs open in the browser, I end up posting the question in stackoverflow as a last resort. What are some time management techniques that lets you stop, rewind and get back in action when faced with a road block?

remote symbolic link / junction

- by Blueberry

Might be a pretty obvious one but have had some trouble finding solid answers. I have a directory on a windows network share containing different versions of an application. I would like to have a link to one of these called 'current', which will be a symbolic link to the directory sitting beside all the other versions and pointing to one of these. Creating this link seems to be more of an issue than I would have thought. Looks like symlink only shows the link on the same machine as where it was created (which is not going to work for obvious reasons) and junction needs to be run on the server which is practically impossible due to various restrictions. What would be the best way to go about this? Would I just need to copy the files twice or can I have a symbolic link which can be created and accessed remotely?

Android dev time vs iPhone dev time

- by Daniel Benedykt

Hi IF someone has to develop the same application for Android and iPhone, is it more difficult to develop in one platform than on the other? Does it take more time? Lets think about the average app. Lists, text , buttons, fetch information from the internet. Thanks

Convert 12hour time to 24Hour time

- by RwardBound

I have hourly weather data. I've seen the function examples from here: http://casoilresource.lawr.ucdavis.edu/drupal/node/991 I'm altering the code to account for airport data, which has a different URL type. Another issue with the airport weather data is that the time data is saved in 12 hour format. Here is a sample of the data: 14 10:43 AM 15 10:54 AM 16 11:54 AM 17 12:07 PM 18 12:15 PM 19 12:54 PM 20 1:54 PM 21 2:54 PM Here's what I attempted: (I see that using just 'PM' isn't careful enough because any times between 12 and 1 pm will be off if they go through this alg) date<-Sys.Date() data$TimeEST<-strsplit(data$TimeEST, ' ') for (x in 1:35){ if('AM' %in% data$TimeEST[[x]]){ gsub('AM','',data$TimeEST[[x]]) data$TimeEST[[x]]<-str_trim(data$TimeEST[[x]]) data$TimeEST[[x]]<-str_c(date,' ',data$TimeEST[x],':',data$TimeEST[2]) } else if('PM' %in% data$TimeEST[[x]]){ data$TimeEST[[x]]<-gsub('PM', '',data$TimeEST[[x]]) data$TimeEST[[x]]<-strsplit(data$TimeEST[[x]], ':') data$TimeEST[[x]][[1]][1]<-as.integer(data$TimeEST[[x]][[1]][1])+12 data$TimeEST[[x]]<-str_trim(data$TimeEST[[x]][[1]]) data$TimeEST[[x]]<-str_c(date, " ", data$TimeEST[[x]][1],':',data$TimeEST[[x]][2]) } } Any help?

Ubuntu One Windows Client 3.0.1 - Sync not connecting

- by Tweezak

I've got sync working at home on Natty and I need to access files at work. I've just installed client 3.0.1 at work on Windows 7. It's finding my account and sees what devices are already set up for sync but it just repeatedly tries to sync (File sync starting...) and after a while fails (File Sync is disconnected.). This cycle loops endlessly. I'm suspicious that it's a problem with my proxy setup. My employer doesn't use a manual proxy configuration but instead uses an automatic configuration script at a specific http address. Does U1 recognize that kind of setup or is it only looking for a proxy server in the form of an address/port?

Laptop takes a long time to boot after Grub menu

- by Andres

I am running a Asus R401VJ laptop (Latin America version of N46VJ) that has a Core i7 CPU and 8GB RAM. After my Grub menu, which is displayed for 2 seconds as I set it up, I'm getting a black screen with a blinking white cursor that is increasing my boot time to about 60 seconds. After a while Ubuntu runs fine, I just want to reduce my boot time. I don't know if this has something to do with my never used Nvidia 2GB GeForce GT 635M graphics card. Always when I tried to install the driver, I ended up with a ~600x800 screen resolution, and I fixed it by deleting a file called: xorg.conf from the /etc/X11/ directory, following a suggestion that I read in another forum. I would appreciate detailed answers, I'm still new at Ubuntu.

Does the Ubuntu One sync work?

- by bisi

I have been on this for several hours now, trying to get a simple second folder to sync with my (paid) account. I cannot tell you how many times I removed all devices, removed stored passwords, killed all processes of u1, logged out and back in online...and still, the tick in the file browser (Synchronize this folder) is loading and loading and loading. Also, I have logged out, rebooted countless times. And this is after me somehow managing to get the u1 preferences to finally "connect" again. I have also checked the status of your services, and none are close to what I am experiencing. And I have checked the suggested related questions above! So please, just confirm whether it is a problem on my side, or a problem on your side.

Mapping local folder with an Ubuntu One folder

- by Titus

TrendMicro's Safesync has a nice feature, you can map your local folder to a folder in the cloud with a different name, e.g: PC1: C:\my_documents\pictures ===> office_pictures c:\my_documents\docs ===> office_docs PC2: C:\my_documents\pictures ===> private_pictures c:\my_documents\docs ===> private_docs Would this be possible with UbuntuOne? The reason is that I have multiple computers, and I don't want all my "my_documents" folders to sync across work and personal life...

Effects of automated time tracking/monitoring [closed]

- by user73937

What are the effects of monitoring the developers' computer usage? (Which program they use - based on the title of the applications - and how much time in a day they use the keyboard and mouse.) Would it has any positive or negative effects on productivity, morale, motivation, etc? It will not have any direct impact on the developers' salary or their performance review it's just for curiosity. The developer and their manager will only see the results. Would it change anything if only the developer is allowed to see the results? The developer can disable the monitoring (for privacy) but it won't count as work time (in the monitoring program).

Managing time for success in the industry? [closed]

- by nvillec

So about a year ago I decided to pursue programming, specifically game development, as a career. I've always been a pretty avid gamer, from chucking turnips at Shy Guys' faces in the 90s, to downing Heroic Deathwing last week. Just recently though, I've been spending a LOT of time playing games and it's starting to show in my programming classes. Yesterday after a discouraging exam, I put my foot down and vowed to myself to keep the gaming:coding ratio in favor of the one that will hopefully pay the bills later on. I realize that knowing games well is a key part of being a good developer, but as I've been recently shown, there's a threshold of pixelated indulgence that must not be crossed if I'm ever going to land my dream job. I'm assuming many of you are quite enthusiastic about games as well. What advice would you give an aspiring programmer regarding time management? Thanks!! (Also, I'm brand new to Stack Exchange...if this belongs somewhere else, I'm happy to move it)

Reduce boot time between grub menu and login screen

- by Sudheer

I use Ubuntu 14.04 LTS version which used to boot fast at beginning but not i loads very slow. I searched for this but can't find suitable answers. so i want to reduce my boot time which is now around 1min 12sec (boot chart) overall but i noticed its taking a longtime after grub menu and before login screen. A Blank screen appears after grub waiting... then login screen appears. I want to know a way to reduce that blank screen time(or if possible remove) and get login screen as fast as possible. I already removed several of my startup applications. Getting desktop after log-in is fast. I don't want to remove unity and install light desktop envinorments like Xfce and Lxde. Here is my boot-chart image Thanks in advance

Ubuntu One doesn't show captcha in windows 7

- by Fredrik Hansson

I try to set up a new U1 account in W7. However, the sign on screen reports "There was a problem getting the captcha, reloading" - but nothing seems to happen. I tried it on two different computers (in the same home network). Same result. Anything to do or is U1 for W7 corrupt? Also experiencing this problem. Trying to install latest U1 on brand new Toshiba Win7 laptops at work and the captcha field is simply blank, there is nothing to copy. Tried refresh, restart, reload and different browsers (Firefox 13, IE9) and nothing improved the situtation. Without being able to see the captcha I cannot do anything at all and will have to use silverlight if I can't overcome this.

Doing port forwarding and then using it from within the internal network

- by Ram Rachum

We all know that by doing port forwarding on the router, computers from outside the network are able, on the specified ports, to access internal computers by targeting the external IP. I'm now replacing a TP-Link router with a D-link VDSL N 6740U router, (and copied over all the settings,) and I've noticed that one thing stopped working: With the TP-link router, you could access those port-forwarded computers from within the network, using the external IP, and they would be forwarded to the relevant computers. With the new D-Link router, it doesn't work. You might be wondering, why would you want to use the external IP and port forwarding when you're inside the internal network anyway and can just access the internal IP? One example for why this is useful: You have an iPhone app that connects to a service on an internal computer. The iPhone app knows to connect to the external IP. When we put that iPhone inside the internal network (via WiFi), it suddenly stops working, because it can't access the service from the external IP anymore. Is it an inherent property of D-Link routers that they do not allow accessing internal servers from inside the network by targeting the external IP? Or is there a way to make it work?

How does one improve one's problem-solving ability?

- by gcc

How can one improve one's problem-solving ability? Everyone says same thing: "a real programmer knows how to handle real problem." But they forget how they learn this ability, or where (I know in school, no one gives us any ability, of course in my opinion). If you have any idea except above ones, feel free when you give your advice solve more problems do more exercises, write code, search google then write more ... For me, my question is like "use complex/known library instead of using your own." In other words, I want your personal experience, book recommendation, webpage on problem solving. Moreover, look your problem-solving method and give us your personal ability as if it is an algorithm

Planning milestones and time

- by Ignas

I was hired by a marketing company a year ago initially for link building / SEO stuff, but I'm actually a Web developer and took the job just in desperation to have one (I'm still quite young and just finished 2nd year of University). From the 3rd day my boss realised that I'm not into that stuff at all and since he had an idea of a web based app we started to plan it. I estimated that it shouldn't take me longer than two months to do it, but as I was making it we soon realised that we want to add more and more stuff to make it even better. So the development on my own lasted for about 4 months, but then it became an enterprise size app and we hired another programmer to work along me. The guy was awesome at what he did, but because I was assigned to be programmer/project manager I had to set up milestones with deadlines and we missed most of them, because most of the time it was too much work, and my lack of experience kept me setting really optimistic deadlines. We still kept adding features and had changed the architecture of the application twice. My boss is a great guy and he gets that when we add features it expands the time frame in which things should be done so he wasn't angry at me nor the other guy. But I was feeling bad (I still am) that I suck at planning. I gained loads of experience from the programming side, but I still lack the management/planning skills which make me go nuts. So over the last year I have dedicated probably about 8 months of work to this app (obviously my studies affected it) and we're launching as a closed beta this month. So my question is how do I get better at planning/managing a project, how do you estimate the times? What do you take into consideration when setting goals. I'm working alone again because the other guy moved from the city. But I'm sure we'll be hiring to help me maintain it so I need to get better at it. Any hints, points or anything on the topic are appreciated.

Spreading incoming batched data into a real-time stream

- by pr1001

I would like to display some events in 'real-time'. However, I must fetch the data from another source. I can request the last X minutes, though the source is updated approximately every 5 minutes. This means that there will be a delay between the most recent data retrieved and the point in time that I make the request. Second, because I will be receiving a batch of data, I don't want to just fire out all the events down a socket once my fetcher has retrieved it: I would like to spread out the events so that they are both accurately spaced amongst each other and in sync with their original occurrences (e.g. an event is always displayed 6 minutes after it actually happened). My thought is to fetch the data every 5 minutes from the source, knowing that I won't get the very latest data. The original data would be then queued to be sent down the socket 7.5 minutes from its original timestamp – that is, at least ~2.5 minutes from when its batch was fetched and at most 7.5 minutes since then. My question is this: is this the best way to approach the problem? Does this problem have any standard approaches or associated literature related to implementation best-practices and edge cases? I am a bit worried that the frequency of my fetches and the frequency in which the source is updated will get out of sync, leading to points where no data will be retrieved from the source. However, since my socket delay is greater than my fetch frequency, the subsequent fetch should retrieve newer data before the socket queue is empty. Is that correct? Am I missing something? Thanks!

What does "link to unknown" mean?

- by Question Overflow

I just upgraded my server to Fedora 17 which made a switch of my bootloader from GRUB Legacy to GRUB2. There are two symbolic links in the /etc folder that points to the files grub.conf and grub.cfg in /boot/grub and /boot/grub2 respectively. Though the targets seem correct, the link icons are displaying an X status which seems to indicate that the links are broken. Upon right-clicking the property type, it states "link to unknown". The file size of the link corresponds exactly with the file size of the target file, so, why does the links appear to be broken? The image of the link icons: As requested, the following are the outputs from the commands: $ ls -l /etc/grub.conf lrwxrwxrwx. 1 root root 22 Jul 14 2011 /etc/grub.conf -> ../boot/grub/grub.conf $ ls -l /etc/grub2.cfg lrwxrwxrwx. 1 root root 22 Dec 10 18:57 /etc/grub2.cfg -> ../boot/grub2/grub.cfg
