Slackware :: No Sound And Possible No Swap
Oct 19, 2010
I got two problems. Problem 1 the sound is kind of sketchy..I thought the sound card got blown. But I heard my friend got sound on it again before we put Slackware on. Next I left him to install it while I went to class. I don't think he put a swap in. The computer is painfully slow and it can't even switch users because it looks like the ram got murdered or something. My Questions are how to test / get a working sound card. I did do the alsamixer I think the command is and turn the volume levels up yet I don't hear anything.
As far as the swap partions I don't there is one but I am not sure how to look / check to where if he made it to small or not at all.

I am running Slackware 13.0 on an computer with low memory (128 MB, i thought). When I type "free -m" in xterm terminal it displays.In the last line it displays only 5 MB used of 687. Is that normal?

I'm using slackware about a month now and two days ago I checked to see the usage of my RAM and I saw that there was no swap, no used, no total, nothing! (how can this be?) swap -s returned nothing, I checked fstab and there was swap there so I entered the line about swap:
"UUID=6ea9269a-6bf7-4486-b481-a54dd3bde314 none swap sw 0 0"
I believe it' s correct. I checked after restart with "free" and the total was ok but used is 0. I copied about 5 GB to see what would happen and still nothing. RAM was nearly full but still no swap used!

While this is the second notebook I've had the luxury of running Slackware on, I have never used the the suspend to RAM / swap functions so all of this is new to me. With this new notebook and new installation of Slackware 13.1 I decided to give it a shot as it's definitely a power sucker. The machine is a Lenovo W510 with an NVidia graphics card running KDE. When I tell KDE to go to Sleep (RAM suspension) it looks like it does so properly by blanking the screen and pushing things to RAM. Is there a way to verify that Sleep is working? Anyway after unlocking the system my mouse pointer is no longer visible, however it is still active as I can hover over items to reveal their popups.
At this point none of my conky displays are transparent anymore, nor are they actively displaying stats. The windows I have set to display with 88% opacity are no longer as such and are completely opaque. It is as if all the custom window settings are ignored. If I move the the mouse towards the bottom of the screen the screen starts to go crazy with this rainbow of colors across the top of the screen and the only way to get out of this is to press Ctrl-ESC to bring up a System Activity window. I have not tried Hibernate yet as I would like to get this resolved first. Is Slackware 13.1 supposed to be able to Sleep/Hibernate with no special configuration and creation of scripts provided that the system can handle these functions?

Slackware 13.0, about to install it. I do have an existing Ubuntu installation with a roomy 5 GB of swap.
In the installer of Slackware, what should I do to use this swap?

Did a fresh install of 13.1 using lvm for the first time. I created swap in the logical volume but forgot to add it when I ran through the install. Do I need to just add an entry to my fstab and then swapon -va?

I have a system with 2G of memory and swap memory of 4G.
This is the output from :
PHP Code:
How could they do to the memory cache to be used as much? Because, occasionally, swap is used and note that the system could use the memory cache does not swap ...

Currently running Slackware64 13.1 on a notebook and for the most part everything works fine. Only problem I am running into is with hibernation, where sometimes it will go into hibernation without a hitch and sometimes it will stall after blanking the screen and never turning off. For the most part pm-suspend.log looks fine every time, whether it goes into hibernation or not. My current system has 12GB of RAM and my swap partition is roughly 12GB. For the most part my RAM usage right before going into hibernation is always under 1.5GB with maybe 600MB floating in the swap partition. Could the size of my swap partition be too small even if RAM usage is nowhere near max?

I use the follow command to create a encrypted swap:
Code:
bash# echo "cryptswap /dev/sda5 none swap" >> /etc/crypttab
and edit the 'fstab' file :
Code:
/dev/sda6 / ext4 defaults 1 1
/dev/mapper/cryptswap swap swap defaults 0 0
That's work fine, but I found the permission of '/dev/mapper/cryptswap' is like this:
Code:
hello@world:~$ ls -l /dev/mapper/cryptswap
brw-rw-r-- 1 root disk 253, 4 2010-05-28 12:55 /dev/mapper/cryptswap
Other users can read the file '/dev/mapper/cryptswap', does it harm the system's security ?

I was reading this tutorial & it shows swap at the beginning of drive. [URL]
Although I've already installed slackware & put the swap at the back of os, I would still like to know the benefits and purpose of putting at the beginning.

I wanted to dual-boot Ubuntu and slackware, and use one swap. Well, I had Ubuntu installed and used installed slackware, and the boot hangs when I try to boot into the latest kernel; it says it's waiting for a UUID = (some random characters. I tried to enter a recovery mode for the latest kernel, and I couldn't even log in as root or my log in.

I often swapped window managers between fluxbox kde and gnome back when I ran ubuntu to suit my needs. When I installed slackware, I picked KDE because of the convenient app suite. I don't wish to uninstall kde but I'd like to be able to pick which environment I use when I swap to a GUI. Something like a flag, startx --fluxbox.

The swap partition says that it is empty. When I installed Slackware I'm sure that I pointed to the right place for the swap. Or does it not show any size because none of it is being used?

While installing slackware64-current, setup cannot find swap space. This is an extreme case pushing limits with a huge GPT partition table. So there is probably some limit on the number of partitions, or partition number, the swap search looks for. Of 41 partitions I made scattered around the number range from 1 to 128, the swap space exists as partition 90. Maybe the problem is it can only check partitions 1-15 because 16 and beyond have to use a different device major number? When I do proceed with the install, /dev/sda90 is listed as a choice. FYI, so many partitions is planning ahead for a multi-boot system. The rest of the install went OK.

I was just given a computer from a coworker and installed the latest Slackware version on it. I then installed Gnome Slackbuild and installed the Nvidia driver.I've run alsaconf and it seems to run fine without any errors and unmuted all the channels in alsamixer.

I'm currently trying to install unRaid on Slackware following this tutorial :[URL].. I'm new to Linux and after many hours, i finally managed to build the new kernel for unRAID (2.6.32.9). But audio on HDMI port doesn't work I tried alsaconf without success. HDMI sound works when i boot into the old kernel.
My codecs are :
Code:
root@unraid:~# cat /proc/asound/Intel/code* | grep Codec
Codec: Realtek ALC888
Codec: Intel G45 DEVIBX
Code:
lspci -v:

RAM for older machines like I use is fairly cheap these days. But flash memory is just as cheap or cheaper. So I'd like to ask about the feasibility of expanding my system's memory using flash memory. And about whether creating a partition for swap on the flash memory, or whether a swap file on the flash device, is the better way to go.
By flash memory I have in mind mainly USB sticks or what are sometimes called "pen drives." But I do also have CF and SD cards that, with the proper cheap adapter (one of which I already own for adapting CF) could be used to create extra swap space. So, what is the current consensus on the feasibility/advisability of using flash memory for swap? I've read about the limited write cycles of flash being an argument against using it for swap. But recent reading indicates to me that the limited write cycles problem applies mostly to older, smaller-capacity flash memory. Some will come out and say that, for larger-capacity flash memory, the life of the device is likely to exceed the amount of time your current computer will be useful (I think I've seen estimates in the range of 3-4 years life--minimum--for newer, higher-capacity flash memory).
A more persuasive argument I've heard against using flash memory for swap is that access times for these devices can be much slower than SATA, and maybe even IDE, hard drives. That would certainly dictate against using flash memory for swap.
So, how about some input on this issue? Anyone using flash memory for swap? If so, what kind (e.g., usb stick or SD/CF)? Are you using a swap file or a swap partition? How's system performance? Likewise, has anyone had flash-memory-used-as-swap die on them? The consequences would undoubtedly be dire. Also, has anyone measured flash memory access times to confirm or refute claims about slow access times? Are some types of flash memory better/worse than others in terms of access times?

I have 2G of physical memory and 1G of memory swap. Very rarely the memory swap is used and when usage is around 1% while, then gets a lot of free physical memory...My question is:It is possible to "clean up" the memory swap. Or better still (I think). It is possible to spendphysical memory for data that is in memory swap?

Today I installed Slackware 13 because of some issues I'd been having with slackware 9, which I'd gradually updated, but apparently not perfectly, hence the clean install of ver 13. Anyways, I have no sound. At first I thought I had no sound at all, but then I found out that audio does work for root. When I try to run alsamixer as a non-root user, I get this error:
Code: alsamixer: function snd_ctl_open failed for default: No such file or directory Now if I run it as root though, it works just fine. If I run the KDE system settings thing, what I guess is their version of the windows control panel, and I go to the multimedia section, I can see my card, but if I click test, it says that it's failed and that it's "reverting back to ." or something to that effect.(I'm in fluxbox right now). I would imagine that there's something I need to do with respect to modifying permissions, but I really don't know what that is that I'm supposed to do.

I recently got a yamaha sound card from a friend because my Intel card was not working so I disabled Intel sound card from BIOS so that I can use only Yamaha card but I hear no sound in Slackware but can hear sound in my Fedora & Windows (i.e.card is working) code...

This problem applies to Konqueror, Firefox, and Seamonkey. It applies equally to all forms of online sound content, from flash to yahoo media player. Yes, the sliders are up in my sound mixer! I have sound from all other apps, just not web browsers. It also applies to alluser accounts.

sound is fine in KDE, but not in Firefox.
Alsamixer shows no capture controls for the device and I get no sound through the browser. I have set the device as default. However, I get sound fine when testing in KDE's System Settings (Phonon). Sound works just fine through Amarok and Dragon Player.
How do I get Firefox to play sound through this device?

I was reluctant to start yet another sound thread, but after days of searching sites and reading mini HOWTO's I'm still mute. I have tried configuring ALSA via:
# alsaconf
# /etc/rc.d/rc.alsa start
# alsamixer - all relevant sliders unmuted...
# alsactl store
...and still nothing. KDE reports that 'Audio playback device ALC889 does not work.' My kmix app doesn't even start. At boot I get this message 3 times:
"ALL CONFIG FILES NEED /etc/modprobe.d/sound - it will be ignored in a future release"
Even starting xmms brings up 'Check that - your soundcard is configured properly/the correct plugin is selected/no other program is blocking the soundcard'. btw, Windows reports I have an ALC888, not a 889. KDE lists it as present as both digital and analog, and the legacy system (whatever it is) as well as esound, but none work. I certainly had no difficulty with S11.
