  • Elementary OS boots to a terminal (other OS) [on hold]

    - by Benjamin Watson
    Im new to this site, please forgive me if I missed some posting protocol of some sort. I am attempting to install Luna on my samsung s2 laptop (a8 amd radeon 7640g) and when I click on try luna, it just pulls up a terminal after the insignia (curvy E). When I install it, same issue. CTRL-ALT-f7 reveals this (hand typed, sorry if there's typos) Starting preload: *starting CUPS printing spooler/server *stopping save kernel messages preload. fsck from util-linux 2.20.1 fsck from util-linux 2.20.1 dosfsck 3.0.12, 29 oct 2011 FAT32, LFN /dev/sda1: 3 files, 245/189518 clusters /dev/sda2: clean, 133841/30294016 files, 2529529/121164544 blocks Skipping profile in /etc/apparmor.d/disable: usr.sbin.rsyslogd *starting AppArmor profiles speech-dispacher disabled; edit /etc/default/speech-dispenser *stopping system V initialisation compatibility *starting system V runlevel compatability *starting apci daemon *starting anac(h)ronistic cron *starting save kernal messages *starting ntp server ntpd *starting regular background program processing damon *starting deferred execution scheduler *stopping anac(h)ronistic cron *starting LightDM Display Manager *starting bluetooth daemon *starting mDNS/DNS-SD daemon *starting CPU interrupts balancing daemon *stopping Send an event to indicate plymouth is up saned disabled ; edit /etc/default/saned *starting network connection manager *starting crash report submission daemon *checking battery state...

Any/all help would be appreciated. Thank you for your time.

  • I can't upgrade to 12.10 Quantal Quetzal

    - by JamesTheAwesomeDude
    After hearing about some of the features in 12.10, I decided to upgrade my Ubuntu from 12.04 LTS to the newer 12.10. However, when I try to upgrade it, I start the update manager, like always, and I start the distro upgrade, just like I do every time there's a new version, but at the end of the "Setting new software channels" stage, it fails, saying: Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade: E: Unable to correct problems, you have held broken packages. This can be caused by: Upgrading to a pre-release version of Ubuntu Running the current pre-release version of Ubuntu Unofficial software packages not provided by Ubuntu If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. What should I do? I understand that I have some sort of "broken" package on my system, but how do I identify and remove the problem? Note: At the start of the "Setting new software channels" stage, I was presented with this: Third party sources disabled Some third party entries in your sources.list were disabled. You can re-enable them after the upgrade with the 'software-properties' tool or your package manager.

  • ASP.NET ViewState Tips and Tricks #1

    - by João Angelo
    In User Controls or Custom Controls DO NOT use ViewState to store non public properties. Persisting non public properties in ViewState results in loss of functionality if the Page hosting the controls has ViewState disabled since it can no longer reset values of non public properties on page load. Example: public class ExampleControl : WebControl { private const string PublicViewStateKey = "Example_Public"; private const string NonPublicViewStateKey = "Example_NonPublic"; // DO public int Public { get { object o = this.ViewState[PublicViewStateKey]; if (o == null) return default(int); return (int)o; } set { this.ViewState[PublicViewStateKey] = value; } } // DO NOT private int NonPublic { get { object o = this.ViewState[NonPublicViewStateKey]; if (o == null) return default(int); return (int)o; } set { this.ViewState[NonPublicViewStateKey] = value; } } } // Page with ViewState disabled public partial class ExamplePage : Page { protected override void OnLoad(EventArgs e) { base.OnLoad(e); this.Example.Public = 10; // Restore Public value this.Example.NonPublic = 20; // Compile Error! } }

  • Why doesn't Bumblebee work with Nvidia GT640M?

    - by Dickson Wong
    I've done a clean install of Ubuntu 12.04 from a liveCD on a Samsung Series 7 Chronos with a 3rd Gen i7 and the Nvidia GeForce GT 640M. I've followed this: (https://wiki.ubuntu.com/Bumblebee#Installation) to install bumblebee so I can switch to my discrete GPU. I have not used ironhide, or preivous bumblee since it's a clean install. When I use optirun, optirun says it can't initialize the GPU: [ERROR]Cannot access secondary GPU - error: [XORG] (EE) NVIDIA(0): Failed to initialize the NVIDIA GPU at PCI:1:0:0. Please [ERROR]Aborting because fallback start is disabled. I've looked at the troubleshooting page for bumblebee and I have the correct driver and do not think I have aspci disabled. Also, my keyboard becomes very unresponsive and my mouse skips and isn't smooth after optirun crashes. The only thing to fix this is a reboot. Here's my lspci | grep VGA output: 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation Device 0fd2 (rev ff) It seems Ubuntu can see my graphics card. I don't really know what's going on.

  • Is there a way to disable the hardware on/off switch for the Wireless interface?

    - by avee
    I have an HP 520 and is running the latest Ubuntu 11.10. The hardware works fine with Ubuntu with one exception: The device has a hardware switch for turning the wifi on and off. Every time the wi-fi is disabled through the hardware switch, I am unable to bring it on again. The message on the networking popup would be device not ready. What I am looking for is a way to disable the hardware switch altogether so that when users accidentally press the button, the wifi would not be disabled. There is no setting to disable the switch in the BIOS.

  • Writing to a D3DFMT_R32F render target clamps to 1

    - by Mike
    I'm currently implementing a picking system. I render some objects in a frame buffer, which has a render target, which has the D3DFMT_R32F format. For each mesh, I set an integer constant evaluator, which is its material index. My shader is simple: I output the position of each vertex, and for each pixel, I cast the material index in float, and assign this value to the Red channel: int ObjectIndex; float4x4 WvpXf : WorldViewProjection< string UIWidget = "None"; >; struct VS_INPUT { float3 Position : POSITION; }; struct VS_OUTPUT { float4 Position : POSITION; }; struct PS_OUTPUT { float4 Color : COLOR0; }; VS_OUTPUT VSMain( const VS_INPUT input ) { VS_OUTPUT output = (VS_OUTPUT)0; output.Position = mul( float4(input.Position, 1), WvpXf ); return output; } PS_OUTPUT PSMain( const VS_OUTPUT input, in float2 vpos : VPOS ) { PS_OUTPUT output = (PS_OUTPUT)0; output.Color.r = float( ObjectIndex ); output.Color.gba = 0.0f; return output; } technique Default { pass P0 { VertexShader = compile vs_3_0 VSMain(); PixelShader = compile ps_3_0 PSMain(); } } The problem I have, is that somehow, the values written in the render target are clamped between 0.0f and 1.0f. I've tried to change the rendertarget format, but I always get clamped values... I don't know what the root of the problem is. For information, I have a depth render target attached to the frame buffer. I disabled the blend in the render state the stencil is disabled Any ideas?

  • Dell Laptop's Bluetooth isn't detected by Ubuntu

I saw other place (I don't remember which site) They said, some times, when in windows, if bluetooth disabled by windows driver, It can't be enabled by linux. So, I should install windows and enable blueethooth from windows and then re install linux. That is impossible for me, because I don't have Windows installation media. But I tried this, which is I installed windows xp on virtual box. Vbox showed me thow unknow USB devices. I connected them and installed windows bluethooth drivers to xp. But it didn't ditected Bluethooth either. Also, when I set off mode in hardware switch, those unknown devices disappear from Vbox usb device seletcion menu. So, they are definitely something to do with wifi or bluethooth. Please help me..

  • Yoga Pro 2 Wi-Fi not working

    - by user293004
    I installed Ubuntu 14.04 on my new Yoga Pro 2 and the wireless is not working. It started with Windows 8 on it. The Network Manager says Wi-Fi is disabled by hardware switch. I tried putting a blacklist file in ect/modprobe.d as has been suggested in many places. I called the file "blacklist-ideapad_laptop.conf" and wrote in the file blacklist ideapad_laptop I checked to make sure that the wireless is enabled in the BIOS. It is. I ran rfkill list all and it displayed: 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 2: phy0: Wireless LAN Soft blocked: no Hard blocked: yes I ran iwlist wlan0 scan and it displayed: wlan0 Failed to read scan data : Network is down I ran sudo rmmod ideapad_laptop and it displayed: rmmod: ERROR: Module ideapad_laptop is not currently loaded.

  • Gnome3 shell video corruption with ATI Radeon HD 4850 on 11.10 Oneiric

    - by AndyAtTheWebists
    I have a problem similar to what's been mentioned in a few other questions, namely: Ati incompatible with Gnome-shell? Gnome Shell Glitched Top Bar Ubuntu 11.10 I have read a number of other posts here and on other forums and have tried a bunch of different solutions. The Problem The problem manifests itself only in Gnome3. I have tried KDE, Unity and KFCE and all are fine. The graphics corruption is visible only on gnome panels (see images below). Everything works fine with the free ATI drivers, but they just lack power. The problem occurs with the proprietary ones from AMD/ATI. I have installed version 11.11 and 12.1 as per the instructions on wiki.cchtml.com/index.php/Ubuntu_Oneiric_Installation_Guide. I have the same exact problem in both cases. I have tried this on clean installs of Ubuntu 11.10 Oneiric Ocelot (x64 and x86) and on Linux Mint 12 (x64) with the same results. Also, it looks like after some time of not using it, the PC just freezes. Maybe an overheat? Will look into it. Things I've Tried I have tried the following fixes: Different versions of drivers from ATI including the latest - this worked for some, not for me. Installing Oneiric specific package generated from driver, as well as the default install Removed the Unity Global menu Disabled file manager handling desktop Disabled Compiz "detect refresh rate" Sync to VBlank in Compiz on and off Please help! This is the first time in 10 years that I've finally had the chance to switch my primary desktop to Linux (stopped doing .NET dev work), and this is really getting me down. This is what the problem looks like: And:

  • Should the syntax for disabling code differ from that of normal comments?

    - by deltreme
    For several reasons during development I sometimes comment out code. As I am chaotic and sometimes in a hurry, some of these make it to source control. I also use comments to clarify blocks of code. For instance: MyClass MyFunction() { (...) // return null; // TODO: dummy for now return obj; } Even though it "works" and alot of people do it this way, it annoys me that you cannot automatically distinguish commented-out code from "real" comments that clarify code: it adds noise when trying to read code you cannot search for commented-out code for for instance an on-commit hook in source control. Some languages support multiple single-line comment styles - for instance in PHP you can either use // or # for a single-line comment - and developers can agree on using one of these for commented-out code: # return null; // TODO: dummy for now return obj; Other languages - like C# which I am using today - have one style for single-line comments (right? I wish I was wrong). I have also seen examples of "commenting-out" code using compiler directives, which is great for large blocks of code, but a bit overkill for single lines as two new lines are required for the directive: #if compile_commented_out return null; // TODO: dummy for now #endif return obj; So as commenting-out code happens in every(?) language, shouldn't "disabled code" get its own syntax in language specifications? Are the pro's (separation of comments / disabled code, editors / source control acting on them) good enough and the cons ("shouldn't do commenting-out anyway", not a functional part of a language, potential IDE lag (thanks Thomas)) worth sacrificing? Edit I realise the example I used is silly; the dummy code could easily be removed as it is replaced by the actual code.

  • Ubuntu 13.04 alongside Windows 8 - How to partition from Windows

    - by mengelkoch
    I plan to install Ubuntu 13.04 alongside Windows 8, and I'm looking for a CLEAR answer on how to conduct partitioning appropriately. I'm very new to all of this so a thorough explanation with minimal jargon would be great. I have an Acer Aspire M5 x64 with 6G RAM. I think I already figured out how to deal with the fast startup, UEFI and SecureBoot issues (I disabled fast startup and disabled Secure Boot). I am able to boot into Ubuntu from a LiveUSB, and I think I am ready to install Ubuntu. Note - despite some advice found here, I do have to disable SecureBoot to boot 13.04 from my LiveUSB. From what I have read here, it seems that I should (at least at first) create the partitions from WITHIN Windows 8, not from the LiveUSB, to avoid reported problems. I have run compmgmt.msc and I see the existing partitions. I see the following: Disk 0: 400 MB Recovery; 300 MB EFI System; Acer (C:) 444.95 GB (Boot, Page File, Crash Dump, Primary Partition); 20 GB Recovery Disk 1: 3.74 GB Primary Partition; 14.90 GB Primary Partition I gather I need to create a mounting point '/' Partition (??), a swap partition, and a home partition. Please explain what these are, how big they should be, how I create them from Windows Disk Management, and anything else I need to know. Eventually, I plan to fully replace Windows 8 with Ubuntu, but for now I want to run alongside Windows 8 and not screw things up. I don't have any critical files saved on this computer yet. Thanks.

  • NVIDIA X Server TwinView isses with 2 GeForce 8600GT cards

    - by Big Daddy
    Full disclosure, I am relatively new to Linux and loving the learning curve but I am undoubtedly capable of ignorant mistakes I have a rig I am building for my home office desktop. The basics: Gigabyte MB AMD 64bt processor Ubuntu 12.04 64bit two Nvidia GeForce 8600GT video cards using a SLI bridge two 22" DVI input HP monitors So here is my issue (it is driving me nuts) with X Server. If I plug both monitors into GPU 0 X Server auto configures TwinView and all is grand, works like a charm, though both are running off of GPU 0. If I plug one monitor into GPU 0 and one monitor into GPU 1, X Server enables the monitor on GPU 0, sees but keeps the monitor on GPU 1 disabled. My presumption (we all know the saying about presumptions) is that all I would have to do is select the disabled monitor on GPU 1 and drop down the Configure pull down and select TwinView...problem is when the monitors are plugged in this way, the TwinView option is greyed out and can not be selected. What am I not understanding here? Is there some sort of configuration I need to do elsewhere for Ubuntu to utilize both GPU's? Any help will be most appreciated, thanks in advance.

  • Automatically revert to laptop screen when external monitor unplugged

    - by Ryan
    I regularly use an external monitor with my laptop, so when I use it, I usually have the laptop screen disabled when the monitor is connected, and this seems to cause problems when the monitor is disconnected. If the monitor is connected while the laptop screen is disabled, I can't get the X session to show up at all: I can Ctrl+Alt+F1 to open a terminal, and that works fine.. ..but Ctrl+Alt+F7 does nothing. The display is blank, and stays blank. The same thing happens whether I put the computer to sleep with the monitor connected, or if I disconnect while the computer is still awake. Rebooting the computer fixes the issue, as does killing Xorg and starting it again, but both of those are sub-optimal since I lose my current session. I'm currently using the open source graphics driver (xserver-xorg-video-ati). This question looks like it might answer my question, but unfortunately hwinfo is no longer available in the apt repository. Is there a way with current tools to automatically detect when the external monitor is disconnected and switch to the laptop display?

  • Problems dualbooting Ubuntu because of UEFI

    - by Koffeehaus
    I have an X-series Asus laptop which I just bough about a month ago. I want to dualboot Ubuntu - Windows. I can easily access LiveUSB with both UEFI enabled and disabled. I heard that there were problems with UEFI, so I disabled it. After I've installed the system I couldn't access it. It just boots to Windows straight. Another unusual thing, that never happened to me before was that the partition editor wanted me to create a BIOS reserved area, which I did, but not at the beginning of the table. Any ideas how to access the Ubuntu partition? As far as I can guess both Windows and Ubuntu have to be both of the same type of boot, either Legacy or EFI. This is not the case of what I have now. So, if I reinstall Ubuntu in UEFI mode that correlates with my Windows type, will I then be able to boot into it? I have a constraint, my laptop doesn't have a CD ROM, so I cannot reinstall WIndows, nor can I move around the Windows recovery partition. This is the boot-repair report : http://paste.ubuntu.com/1354254/

  • How can I get a user account back?

    - by Ilan
    With all my computers I make one partition for the root and another for /home. This is useful for disasters where I need to reformat the root for ubuntu, but leave my /home data untouched. With the upgrade to 13.10 I had troubles on my wife's computer so I reinstalled 13.10. My own /home files came up, as expected, as if nothing had happened. For my wife, it is a different story - and that is the part where I need help. If I go into Files, computer I can see the home directory. There I can see ilan (my files) and yona (my wife's files). I can open yona, documents and see all her work. This means that all is well and I just need to hook up to her files. So the problem is that I need to create a user called Yona or yona, but something which will get me to exactly the files of interest. I'm not sure if I created her account as standard or an administrator. Is there any way I could tell by looking at the files in /home? I created a new user called Yona as a standard user (hoping that this is the right guess). The account came up as disabled. I pressed on the disabled button so I could change the password. I put in her password but it was refused as too short. Too short, too short, but that is what was used and that is what I need. Can anyone help me before my wife comes home and shoots me? Thanks, Ilan

  • Why is Ubuntu unmounting my primary hard drive?

    - by Twisol
    I'm running Ubuntu 10.10 on my laptop (an Asus G73j), dual-booting Windows 7 if that matters. After using the computer for couple of hours or so, I get a popup complaining that a file was unmounted, then my GNOME desktop panels disappear. I can't save any unsaved work (the file browser shows "Filesystem" as totally empty), and other programs break in odd ways (like Chrome can't browse to any new pages, but keeps current ones going... at least I still have Pandora to listen to when this happens!). I've tried looking in the system logs to no avail; I'm assuming that it can't write any errors to the logs because, of course, the logs are on the primary hard drives. This started happening maybe a few days ago. Yesterday I upgraded from 10.4, but I believe it was happening before then. Any advice for figuring this out? EDIT: It just happened again, and I heard a small little clicky sound from the hard drive about five seconds before things went south. I'm thinking I should start backing up ASAP. In response to a comment, here's the dmesg output: http://askubuntu.pastebin.com/uYGshBay Also, the SMART status says the disk has a few bad sectors, and the detailed data says there are 14. It says it passed the self-assessment though. Lastly, this doesn't seem to be happening when I'm on Windows. I recently re-enabled ureadahead (which I disabled ages ago because it was causing Ubuntu to hang at the startup logo), could that be the source of the problem? I've disabled it again to see.

  • How to set individual NTFS partitions permissions behaviour for each user account?

    - by ryniek
    I have two NTFS partitions (DOWNLOADS for downloaded files and VM for my VirtualBox .vdi file) for which i must have full permissions for my allday use account. They should be also automounting when i login to this account. But i've also set Guest account for guests. For Guest account, i want make VM partition fully disabled and invisible (and thus it mustn't automount) but DOWNLOADS partition should be shared with limited privileges with Guest account. Editing fstab i'm able to share DOWNLOADS partition with Guest on limited privileges but VM can be only set to limited and have disabled automounting - so guest can't mount it but it still can be seen in Nautilus, plus I must always mount it manually when i login to allday account. Is there some trick to make what i want? Here's my fstab config: # /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 #Entry for /dev/sda1 : UUID=35e66658-5ee9-40cf-bf56-8204959e3df0 / xfs defaults 01 #Entry for /dev/sda2 : UUID=26c714cf-4236-45e7-9c46-cfcf91a215ae /home xfs defaults 02 #Entry for /dev/sda5 : UUID=1315BCB027C44639 /media/DOWNLOADS ntfs-3g auto,uid=1000,gid=1000,umask=0022,nodev,locale=pl_PL.utf8 0 0 #Entry for /dev/sda6 : UUID=60FF39EB72B72264 /media/VM ntfs noauto,uid=1000,gid=1000,umask=0077,nodev,locale=pl_PL.utf8 0 0 #Entry for /dev/sda7 : UUID=c52411f5-105c-45d1-971f-412f962c350e none swap sw 0 0 /dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0 Thanks

  • Bug: unable to handle kernel NULL pointer dereference at

    - by maria
    I have recently installed new system on my disc, Ubuntu 12.04. Installation proceeded without problems, I started installing additional software and put data from other discs. I had already two times bug report, it was quite long, and I have no idea how to acces to log file (which probably is somewhere saved) and since I had to switch off the computer using the button, anything else was possible, here is just a small part of it (what I've noted on paper) could not write bytes: Broken pipe speach dicpatcher disabled: edit etc/default/speach-dispatcher saned disabled: edit .... and than: BUG: unable to handle kernel NULL pointer dereference at 0000009c I've run Memory test in GRUB, everything is fine. First time it occured when I was using rsync, second time when I was trying to install texlive. Should I install whole system once again? Or can it be hardware problem? Or something else? If there is any hardware details which may be relevant, please ask, since I have no idea what is happening, I don't know what kind of information could be useful. Thanks P.S. dmesg output:

  • Prevent Changing the Screen Saver and Wallpaper in Windows 7

    - by Mysticgeek
    Sometimes you might not want users to have the ability to change Screen Savers and Wallpaper on Windows 7 workstations. Today we look at how to prevent them from changing either one or both. You might administer computers in your home or small office and find it annoying when users continuously change the wallpaper and Screen Savers to something obnoxious. A lot of times they might be inexperienced users and download these so-called “wonderful and free” Screen Saver/Wallpaper packages from shady sites that include loads of Spyware. Preventing users from changing them is another helpful tool to avoid wasteful time spent switching things back. Prevent Changing Screensavers & Wallpaper Using Group Policy Editor  Note: This method uses Group Policy which is not available in Home versions on Windows 7. Open the Start Menu and enter gpedit.msc into the Search box and hit Enter. When Local Group Policy Editor opens, navigate to User Configuration \ Administrative Templates \ Control Panel \ Personalization. Then in the right column double-click on Prevent changing desktop background. Now check the radio button next to Enabled, then click OK. Back on the Group Policy Screen, double-click on Prevent changing screen saver. In the next screen select the radio button next to Enable, click OK, then close out of Group Policy Editor. Now when a user goes into the Personalization section, the Desktop Background hyperlink is now grayed out and inactive. Notice the message One or more of the settings on this page has been disabled by the system administrator at the bottom of the section. If they click to change the Screen Saver, an error message will pop up letting them know the function is disabled. Prevent Changing Screensavers & Wallpaper Using a Registry Hack You can also make a couple Registry changes to prevent users from changing the Wallpaper & Screen Saver…which will work on Home versions of Windows 7. Before making any Registry changes make sure you back it up first. Open the Registry by typing regedit into the Search box in the Start menu and hit Enter. First we’ll start with the Wallpaper. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System and create a new String Value and name it Wallpaper. Then modify the Value data to point to the location of the Wallpaper you want it to always be. Where in this example it’s our main wallpaper on our local drive…then click OK. Now let’s make sure they can’t change the Screen Saver. In the same Registry location, we need to make a new DWORD (32-bit) Value. Give it the Value name of NoDispScrSavPage and the value data of “1” and click OK. Close out of the Registry and restart the machine or simply log off then back on again for the changes to take effect. Results For the Wallpapers, a user can still go in and see the selections, however if they try to change it to something else… It will just go back to the Personalization screen and no changes will be made, as we set the value to only be the background we specified. If the user tries to make a change to the Screen Saver, the hyperlink will be grayed out and inactive, and the message One or more of the settings on this page has been disabled by the system administrator will be displayed at the bottom of the section. Conclusion If you’re tired of users changing the Wallpaper and Screen Saver, and want another way to help avoid Malware, locking down these settings can help a lot. Again, before making any changes to the Registry, make sure to back it up. These settings should work in Vista and XP as well.

  • Why does a bash-zenity script has that title on Unity Panel and that icon on Unity Launcher?

    - by Sadi
    I have this small bash script which helps use Infinality font rendering options via a more user-friendly Zenity window. But whenever I launch it I have this "Color Picker" title on Unity Panel together with the icon assigned for "Color Picker" utility. I wonder why and how this is happening and how I can change it? #!/bin/bash # A simple script to provide a basic, zenity-based GUI to change Infinality Style. # v.1.2 # infinality_current=`cat /etc/profile.d/infinality-settings.sh | grep "USE_STYLE=" | awk -F'"' '{print $2}'` sudo_password="$( gksudo --print-pass --message 'Provide permission to make system changes: Enter your password to start or press Cancel to quit.' -- : 2>/dev/null )" # Check for null entry or cancellation. if [[ ${?} != 0 || -z ${sudo_password} ]] then # Add a zenity message here if you want. exit 4 fi # Check that the password is valid. if ! sudo -kSp '' [ 1 ] <<<"${sudo_password}" 2>/dev/null then # Add a zenity message here if you want. exit 4 fi # menu(){ im="zenity --width=500 --height=490 --list --radiolist --title=\"Change Infinality Style\" --text=\"Current <i>Infinality Style</i> is\: <b>$infinality_current</b>\n?
