Chaque constructeur a ses astuces selon le type de matériel. Sur les fixes, il y a bien souvent un strap ou un coup de tournevis entre 2 soudures. Pour les portables, et plus encore pour les tablettes il y a souvent des combinaisons digne d'un jeu vidéo, genre combinaison d'actions improbables pouvant impliquer des appuis de touche, utilisation des touches de volume, maintient du bouton marche pendant 35 secondes, succession de codes... Bref, chercher sur internet, c'est rare qu'on ne trouve pas, souvent su Youtube d'ailleurs.
Re: Pas le mot passe bios?
J'oubliais un détail important : Potentiellement, un reset du bios peut entraîner un reset du système en «configuration d'usine» si le système est chiffré quelque part. Donc toujours sauvegarder ses données avant !

It could be a case where the window manager (xfwm4) died or failed to start for some reason. If the system is configured to remember what applications were running when you exit a session, future logins will not have xfwm4, either. I'm not running Xfce at the moment, so I can't give you exact instructions. But if you start the settings manager, look for "session" and click on that. Then click on the tab for current applications and see if xfwm4 is listed there. If it is, then my guess is wrong and the problem is something else. If it is not, start xfwm4 by hand, and everything should be good. mike

Re: Pas le mot passe bios?
Bonsoir Attention avec le retrait de la pile de la carte mère. J'ai rencontré un pc (fixe) avec un mot de passe BIOS inconnu. J'ai tenté cette manipulation, très classique, dessus. Résultat : la carte mère a brické. Il y avait un dispositif de blocage la rendant inexploitable (un message d'erreur disant explicitement que la pile à été retirée, et refus de donner l'accès au bios, ni même démarrer). C'est vraiment vicieux, il faut l'admettre. Mais aujourd'hui, avec toutes les protections contre le boot avec du code malveillant, les sécurités antivol, ce genre de bêtise pourrait être plus fréquent qu'il y a 15 ans (date approximative de mon expérience). Il vaut mieux s'appuyer sur le déblocage avec un mot de passe constructeur, comme décrit en 1ere réponse.

Re: Xfce destop environment
Hi William, xfce configuration files relevant to your user session are stored in your home dir. you can more or less just delete / move the config files and they should get recreated upon logging in to a xfce session. I searched on google for "reset xfce configuration" and found many posts like this: https://forums.linuxmint.com/viewtopic.php?t=122332 "Open a terminal, back up your current configuration: Code: Select all mv ~/.config/xfce4 ~/.config/xfce4.bak Then either leave it like that, which will reset to a default Xfce desktop (no Linux Mint customizations), or copy the skeleton files with the following command, which will reset to a default Linux Mint Xfce desktop: Code: Select all cp -r /etc/xdg/xfce4 ~/.config Then log out and log in again to effectuate the new configuration." I believe you good get results in such a way. It also might be just smth small which is broken. Could you describe "broken" some more? A panel might be hidden but u can access all xfce configuration panels by right clicking on the empty desktop open a menu, than applications follwed by settings. Also take a look at the xfce project documentation, it's quite large with many screenshots to demonstrate the principles of xfce https://docs.xfce.org/xfce/getting-started#the_desktop_environment Nearly everything is just a right click from configuration separated. You could also create a new user account with xfce configured as default session and copy your files over :) Good luck :) Cheers, Martin On 2023-01-30 19:57, William Torrez Corea wrote: On Mon, Jan 30, 2023 at 12:43 AM David wrote: On Mon, 2023-01-30 at 00:07 -0600, William Torrez Corea wrote: What happened with my desktop environment?

laptop freezes randomly - please help!! dell xps 15 with debian testing
Hello, Sorry for starting a new conversation, the previous one didn't help me and I hope that now I have more details. I don't have any idea how to approach that, its my workstation and the past few days I just couldn't really work. I'm also not experienced with this mailing list and a bit confused how to reply here. I hope this time I will do it right. In the past week my laptop freezes randomly, I can say it happens every 2-3 hours. but there are actions that consistently always cause a freeze, like opening Zoom or executing lspci in Terminator. Its a dell xps 15 7590, Intel® Core™ i9-9980HK × 16, 64.0 GiB memory, Mesa Intel® UHD Graphics 630 (CFL GT2), The laptop is attached to a dell docking station wd19 with an external monitor and keyboard and external mouse. It's running Debian GNU/Linux bookworm (debian testing) with Gnome. I've been using this laptop for the past 3 years with the same setup with debian testing since its new. two month ago an official Dell technician replaced the keyboard and fans and cooling board while still under Dell warranty. The freeze started a few days ago after I did full-upgrade. Since then I did full-upgrade again a few times hoping that it's a bug that was fixed but it's still freezing. I always have a few projects open in Jetbrains Intellij idea and rider. I configure Intellij with 20GB memory, always a few browser windows open with many tabs, usually brave and chromium. I always have a few windows and tabs open in Terminator. and more. The freeze always happens as a result of some UI action. examples are when i tried to open settings, or some action in Intellij idea. It's completely random and happens with other applications too. there are actions that always cause a freeze, i tried that again and again restarting the computer every time and it's always the same result, and something suspicious with terminator: trying to open the Zoom app always causes a freeze, I use zoom regularly and there was never a problem until a few days ago. trying to execute the command lspci in Terminator always causes a freeze, everything else in terminator works. executing lspci in Gnome terminal works, that looks to me very suspicious. I tried that at least 10 times to make sure that it's not a coincidence and it's always the same, typing lspci in Terminator and then Enter freezes the computer, but not in Gnome terminal. What I did: As suggested to me here, I connected an ssh session with top and journalctrl -f from another computer and waited for a freeze. I have the latest messages from both at the bottom of this message. I started the computer with a gnome classic session, same thing, computer freeze. started with xfce session, same thing. I ran the Dell pre-boot performance test including a full memory test and it passed OK. I removed all the devices connected like external mouse and keyboard and same thing. I detached the laptop from the docking station and the computer freezes when trying to open zoom or execute lspci in Terminator. I hope someone can help in finding the cause of that freeze. this is info i collected This is journalctrl from another computer in ssh session just before the computer freeze, the freeze was exactly at 16:39 Jan 30 16:38:57 xps-debian jetbrains-idea-ce.desktop[82252]: java.lang.RuntimeException: Cannot invoke (class=, method=projectClosing, topic=ProjectManagerListener) Jan 30 16:38:57 xps-debian jetbrains-idea-ce.desktop[82252]: at com.intellij.util.messages.impl.MessageBusImplKt.invokeListener(MessageBusImpl.kt:639) Jan 30 16:38:57 xps-debian jetbrains-idea-ce.desktop[82252]: at com.intellij.util.messages.impl.MessageBusImplKt.executeOrAddToQueue(MessageBusImpl.kt:466) Jan 30 16:38:57 xps-debian jetbrains-idea-ce.desktop[82252]: at com.intellij.util.messages.impl.ToDirectChildrenMessagePublisher.publish$intellij_platform_core(CompositeMessageBus.kt:295) Jan 30 16:38:57 xps-debian jetbrains-idea-ce.desktop[82252]: at com.intellij.util.messages.impl.MessagePublisher.invoke(MessageBusImpl.kt:421) Jan 30 16:38:57 xps-debian jetbrains-idea-ce.desktop[82252]: at jdk.proxy2/jdk.proxy2.$Proxy97.projectClosing(Unknown Source) Jan 30 16:38:57 xps-debian jetbrains-idea-ce.desktop[82252]: at com.intellij.openapi.project.impl.ProjectManagerImplKt.fireProjectClosing(ProjectManagerImpl.kt:1040) Jan 30 16:38:57 xps-debian jetbrains-idea-ce.desktop[82252]: at com.intellij.openapi.project.impl.ProjectManagerImplKt.access$fireProjectClosing(ProjectManagerImpl.kt:1) Jan 30 16:38:57 xps-debian jetbrains-idea-ce.desktop[82252]: at com.intellij.openapi.project.impl.ProjectManagerImpl.closeProject(ProjectManagerImpl.kt:426) Jan 30 16:38:57 xps-debian jetbrains-idea-ce.desktop[82252]: at com.intellij.openapi.project.impl.ProjectManagerImpl.closeProject$default(ProjectManagerImpl.kt:369) Jan 30 16:38:57 xps-debian jetbrains-idea-ce.desktop[82252]: at com.intellij.openapi.project.impl.ProjectManagerImpl.closeAndDisposeAllProjects(ProjectManagerImpl.kt:362)

I set the linux console mode with via a grub config option in /etc/default/grub. i.e. GRUB_GFXPAYLOAD_LINUX=keep Which I believe stops grub changing the display mode before starting linux, and linux itself just uses whatever mode the hardware is set to. -- Tixy

Re: ecran vide après la connexion
Hello, Que donne 'lspci -kv' sous root ? As-tu essayé un live-cd pour voir si le problème est identique ? s.
ecran vide après la connexion
hello Je suis entrain d'installer debian 11 sur un ordi et j'ai des soucis avec l'affichage. Après l'install, l'affichage est mauvais : basse résolution, images étirées, glxgears avec un score bas et le ventilo qui se met a tourner a fond pendant que glxgears tourne. C'est des symptomes que je connais : problème de pilote de la carte graphique. C'est une carte [AMD/ATI] RV620/M82 [Mobility Radeon HD 3450/3470] Coté pilote, xserver-xorg-video-radeon est déjà installé. Coté firmware, je rajoute non-free au sources.list, j'installe firmware-linux-nonfree (ca installe plusieurs firmwares dont firmware-amd-graphics). Je redemarre. J'obtiens l'écran de connexion, avec des cases pour taper le login et le mot de passe sur fond bleu avec le logo debian. Je tape mon login et mon mot de passe… et j'obtiens l'image de fond bleue avec le logo debian (la meme que sur l'écran de connexion) avec la fleche de la souris au milieu. Et puis c'est tout. Si je bouge la souris, la fleche bouge, mais rien d'autre ne se passe, meme si j'attend longtemps, meme si j'appuie sur une touche du clavier comme entree, ou espace, ou autre. je fais ctrl-alt-F1, j'obtiens un shell, je m'y logue en root. dmesg ne m'apprend rien, htop non plus. Si je fais alt-F7 pour retourner dans l'interface graphique, rien ne change a l'écran mais je perd totalement la main et je suis obligé d'eteindre l'ordi en tirant la prise parce que plus rien ne répond. J'ai cherché sur le web, je suis tombé sur plein de trucs qui disent d'installer le firmware (c'est fait) ou d'installer le pilote proprietaire avec une procedure périmée datant d'avant systemd. J'ai essayé d'éditer, ou meme d'effacer le xorg.conf mais… y'en a plus depuis que systemd est arrivé. Je sais plus quoi faire, en particulier je sais pas comment investiguer pour affiner mon diagnostic. J'ai un écran bleu avec la fleche de la souris au milieu, je n'ai aucun message d'erreur a taper dans google. Si quelqu'un a des bonnes idées je suis preneur.
Opencv quelqu’un pour me donner l’info ?
Slt,

Est ce que quelqu’un peut me dire ce que donne ca (sur les fichier dans la
dropbox ? :
from skimage.metrics import structural_similarity
import cv2
import numpy as np
first = cv2.imread('clownfish_1.jpeg')
second = cv2.imread('clownfish_2.jpeg')
# Convert images to grayscale
first_gray = cv2.cvtColor(first, cv2.COLOR_BGR2GRAY)
second_gray = cv2.cvtColor(second, cv2.COLOR_BGR2GRAY)
# Compute SSIM between two images
score, diff = structural_similarity(first_gray, second_gray, full=True)
print("Similarity Score: {:.3f}%".format(score * 100))
# The diff image contains the actual image differences between the two images
# and is represented as a floating point data type so we must convert the array
# to 8-bit unsigned integers in the range [0,255] before we can use it with
OpenCV
diff = (diff * 255).astype("uint8")
# Threshold the difference image, followed by finding contours to
# obtain the regions that differ between the two images
thresh = cv2.threshold(diff, 0, 255, cv2.THRESH_BINARY_INV | cv2.THRESH_OTSU)[1]
contours = cv2.findContours(thresh, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
contours = contours[0] if len(contours) == 2 else contours[1]
# Highlight differences
mask = np.zeros(first.shape, dtype='uint8')
filled = second.copy()
for c in contours:
area = cv2.contourArea(c)
if area > 100:
x,y,w,h = cv2.boundingRect(c)
cv2.rectangle(first, (x, y), (x + w, y + h), (36,255,12), 2)
cv2.rectangle(second, (x, y), (x + w, y + h), (36,255,12), 2)
cv2.drawContours(mask, [c], 0, (0,255,0), -1)
cv2.drawContours(filled, [c], 0, (0,255,0), -1)
cv2.imshow('first', first)
cv2.imshow('second', second)
cv2.imshow('diff', diff)
cv2.imshow('mask', mask)
cv2.imshow('filled', filled)
cv2.waitKey()
( je veux faire un script pour me gerer du hdr dans une data base, mais je
cherche comment detecter les images similaire, j’ai lance un fil sur gid hup
mais je dois pas etre claire il propose une cles de hash par fichier !)
D’apres MikeRobinson :
convert -append `counter=0; for x in in-*; do if [[ $(($counter % 2)) == 0 ]];
then echo $x; fi; counter=$((counter + 1)); done` out.jpg
Pour le script avec imagemagick, y a des script pour assemblee les images
d’etoiles ! Mais peut etre quelqu’un connait mieux ?
Merci

Initramfs/ Initrd Resolution
Hello, I have setup a Laptop with 3K display (2880 x 1800 pixels). In Grub I can set the Resolution with gfxmode. Is there an option to setup the resolution in the Initramfs (initrd)? Best regards

Many system services require entropy much earlier than this — this service is hence of limited use for complex system. It is recommended to use a bootloader that can pass an initial random seed to the kernel to ensure that entropy is available from earliest boot on, for example systemd- boot(7), with its bootctl random-seed functionality.
